Sorry folks, there's someone spamming the comments. Trying to get rid of them...

@sjpp71 28 дней назад

It's always a good Monday when there's a new Ed's review to watch! Looks like a very solid scope, with its "hoops" and all. Seems like a great replacement for an ST80.

@k-d-n 28 дней назад

I have the Svbony 503 102ed - 102mm ED refractor and I am extremely happy with it. I use it for narrow band, so the chromatic aberration does not effect me. It is so low maintenance and easy to use, that I hardly use my SCT or newton anymore.

@supermario8416 28 дней назад

Ed if possible please also review the Svbony 102 ED and 122 ED triplet. They are relatively cheap but I wonder about their optics quality.

@hashtaglobotomy2655 25 дней назад

I also am super curious about Eds opinion on the Sv550 series, the Sv503's also.

@ultrametric9317 28 дней назад

I will say something nice about Svbony here. I bought a 6x30 RACI. First look through it was GAH!!! The crosshairs were completely out of focus at the edge and the field stop was total mush. So I disassembled the eyepiece and found two identical achromats - the eyepiece was a Plossl, the first I'd ever seen in a finder. But it was assembled completely wrong - the spacer that belonged between the achromats was in front of them, and they were touching each other, AND facing the same way. Once I got this straightened out, the field stop was razor sharp and black and the crosshairs absolutely perfectly sharp and black edge to edge. I wrote about this on Amazon and Svbony offered to send me another one without a return. I declined. They said they would make a note for their assembly workers in the future. That was excellent customer service.

@chrimony 28 дней назад

Good that they react to the reviews, but I think most of the work was on your end diagnosing their manufacturing problems :)

@1dcbly 28 дней назад

Hi Ed. For a cheap Alt-Azimuth mount take a look at the Svbony SV225. Price between $150 and $130 on eBay or Amazon.

@meibergstrmandersen9181 28 дней назад

As always a pleasure to see your videos Ed. Nice review.

@deep_space_dave 27 дней назад

Thanks for the review Ed! SVBONY does have an actual "Astrophotography" quality 80mm APO scope SV550 which can be had for $700 on Amazon right now. This scope is said to have S-FPL51 low dispersion ED glass which should help take care of the violet stars and I have heard this scope is pretty good. For a little more you can even get it bundled with a 1x flattener at a price that is still cheaper than the Astronomics version of the same scope which doesn't list as having the Ohara glass!

@bill5982 2 дня назад

I just got mine today and just like yours there was play in the focuser. I tightened the screws down (it requires a small hex and you have to put it deeply into the screw heads). The play was removed. The main focuser is movable but somewhat tight, but the fine one works perfectly. So get close with the main focuser and finish the focus with the fine one. The telescope looks light but it is dense and weighs more than it looks. I weighed it at about 6.4 lbs (the bathroom scale is kinda iffy). The vixen plate is removable (again with hex screws) so you could replace it but you may have to drill a hole or two in a new plate to match up with the screw holes. I am waiting for a dovetail clamp to arrive so I can use it with my camera tripod (I bought a good one). Or my goto mount for a Meade DSX-125 Mak mount (the telescope has some issues in that the glue holding the flat right angle mirror came unbound and the mirror is rattling around inside). Or the LDX-55 mounts which were overloaded by the 10 inch Schmidt Newtonian and the 6 inch EMC refractor. An 8 pound short tube refractor should not overload the mounts.

@AstroSoundscape 28 дней назад

Hey Ed - I've been using the 503 ED 102mm of this and on the whole have been pleasantly surprised especially given the price point of the field flattener. One of the quirkiest things Ed is the name, it actually stands for Saturn-Venus-Birding-Orion-Neptune-Youth......no really it does check it out. Cheers, Ollie.

@raylilliquist3275 27 дней назад

I have this scope. If you look down the tube there are no light baffles as you would find in the SV503. My focuser was loose on mine when I received it but I was able to adjust it out using the 6 set screws on the focuser turning them just so slightly all the way around until the play was gone. The hairy stars are from the front optics not being painted black on the sides of the lenses. I corrected mine by 3D printing a 90mm X 5mm ring to friction fit covering the edge of the lense blocking the stray light. I use a Sv605cc OSC with mine and get nice results. I think it is an excellent scope for a beginner getting into astro.

@edting 27 дней назад

Hey thanks for that. Strangely my FS102 also does that notched/flaring aberration to brighter stars and I can't figure out why it's doing that.

@natecuenca8951 27 дней назад

Ed- Your telescope reviews and videos are excellent! Very informative and concise. Been watching the channel for a while. Love it!🔭🔭🔭💫

@BurningFlame1999 28 дней назад

The 102 ED doublet and 122 ED triplet are the best and most interesting Svbony refractors.

@kevinhaynes9091 28 дней назад

Hi Ed, very interesting little scope. I'm a big fan of the Orion ST80; so much so in fact, that I have three of them! A couple of the ST80-A, and an ST80-T. When I was able to afford something better, I none-the-less decided to hang on to them. I did however, upgrade my original ST80-A with a GSO86 Crayford 2" dual speed focuser and Long Perng Correct Image Amici Prism Diagonal, all mounted on the venerable Vixen Porta II. These upgrades would put it in the same price category as the SVBONY without the discount. I must say though, that the GSO focuser is as solid as a rock, with no wobble, and is a huge improvement on the original, and I believe better than the fiddly one supplied on the SVBONY. It's just a shame that the Orion ST80 isn't always available, as seems to be now true for the Porta II. My modest ST80 setup also celebrates the Asian contribution to amateur astronomy, representing Synta, Guan Sheng Optical, Long Perng and Vixen. My upgraded ST80-A will always be a proud member of my telescope collection...

@AstroDenny 27 дней назад

Great review, as usual. This brand has made a pretty impressive name for itself as a budget friendly gateway into OTAs and even cameras. A member in my local club has produced some really amazing images with these scopes. Thanks!

@charlesstrang2346 27 дней назад

Thanks for the fix. I got one for Xmas, and the play in the focuser freaked me out. I will try to adjust mine. Thanks again

@3dfxvoodoocards6 28 дней назад

Interesting video. I have the Svbony 102/714 mm F7 FPL51 doublet, it has a much better image quality than the 102/1000 mm F10 achromat I owned before. It also has a very nice 1:10 focuser, much better than the ones typically used on achromats.

@ultrametric9317 28 дней назад

Classic Japanese refractors also have small (almost invisible!) screws for adjusting the rack and pinion. This usually only needs to be done once. I am glad to see rack and pinion focusers again!

@siberx4 28 дней назад

I have been reasonably impressed with Svbony gear. It is cheap, as you say, but generally serviceably well constructed and definitely alright for anything non-critical when it comes to astronomy accessories.

@mariospenard5125 28 дней назад

@astrofire68 28 дней назад

Very informative review Ed. Thank you. I’ve been looking at SVBONY’s scopes for a couple of years but just haven’t gained the strength to pull the trigger on one. I just want a cheap travel scope with reasonable optics. I think I will roll the dice on this model and see what I get.

@pstanyer1 28 дней назад

Great review, the more expensive svbony ones do seem to get good reviews as well

@jeffreystyles9472 28 дней назад

@edting 28 дней назад

Me too!

@Neanderthal75 28 дней назад

They seemed they started off selling parts and accessories for telescopes (finder shoes, filters, dovetails) and they had a relatively inexpensive 70mm achromat which became popular with the amazon shoppers. I mean you can look around and find very low quality usual junk stuff you'd see in department stores with plastic tubes and just bad optics. meanwhile Svbony offered an OTA with metal tube and coated optics, which may not sound very exciting to seasoned hobbyists but among the rest of the junk, it is a better quality telescope. Their biggest hit is still the ED80- 80mm doublet though. It came out just before the covid and got popular during the pandemic, as many scopes became hard to buy due to halting their production, but Svbony had a stock and easily sold them through amazon. The 80mm also got popular, because its aggressive/cheap pricing compared to other telescopes with similar performance. Currently they also have an 80mm triplet and a 122mm triplet and both for less than the other/bigger brands. I got the 80mm triplet version and it's my workhorse for narrowband and wide view imaging. Zero problems, no strange colors, no strange star shapes. It works as it supposed to.

@fermoCR 27 дней назад

I recently bought SVBony eyepieces, diagonal and red dot finder, and I got to say they are amazing. They even managed to breathe life into my Powerseeker 127 (YES, THE MOST HATED TELESCOPE) and made it useable (well, after a lot other mods I made myself as well) Ed like always you are a treasure.

@ninnymonger 19 дней назад

I too have the 127 Powerseeker and I have made MANY changes and additions to it. I’d be curious to know what you have done. I put the ota on an Orion EQ13. I mounted the rings on a vixen compatible plate. I put a new finder scope bracket and have a RACI fine scope and a Telrad. I’m in the process of upgrading the focuser.

@sfskol9173 7 часов назад

I also have a PowerSeeker 127. Very disappointed with it. Thought of making a beer keg out of it. What mods have you made? (Love all my SvBony stuff including this SV48P)

@fermoCR 6 часов назад

@@sfskol9173 honestly I don't recommend it for a beginner. Top to bottom changes are needed and mine is from 2006 which is less terrible than the new ones. The most important is you need another tripod that can actually carry the weight, I use the included tripod with a SV408 and got a nexstar alt-az for this one. Some my mods to the powerseeker hardware - Filled tripod legs with chromite sand. - Removed the wonky rivets of the tray assembly and reassembled with M4 screws, washers and safety nuts - Dissasembled EQ mount and replaced plastic washers with copper ones and added needle thrust bearings on RA and Dec axis. Made the movement really smooth. - Printed a Vixen mount adapter on my 3D printer. On the OTA: - I flocked the tube inside - Added a Vixen Dovetail plate to spread the rings further apart. - replaced the rubber grommets in the primary mirrors with springs to make collimation easier. - Added spacers with aluminum tape inside the focuser to remove play. - Painted every internal part Musou Black. Painted the outside edges of the mirrors and the corrector lens in the focuser with Musou Black. - Threw away the included eyepieces, Barlow and finder scope and replaced with SVBony parts. It was too much work that I only did for the challenge. Frankly if you want a solution that works out of the box, buy something else 🤣🤣

@fermoCR Час назад

@@sfskol9173 It's too much work to get it in good shape, unless you like a challenge. I improved the tripod, but to use with my svbony SV48. Overall get a better mount/tripod and touch up everything top to bottom: OTA: Flocked the tube, painted most international components with Musou black, including mirror edges, screws and nuts, focuser components and the edge of the corrector lens in the focuser, shimmed the focuser slightly to remove play and painted it. Mount: used copper washers and needle thrust bearings to improve movement smoothness, filled legs with chromite sand, added steel reinforcement plates. Disassembled the accessory tray assembly removing the rivets and instead addes M4 screws with safetynuts and washers to remove lateral play.

@earthling-fh2mg 27 дней назад

I bought the 420mm, 70ED about a year ago, new, for £195. It is a great scope. I then bought the flattener/reducer (for the 80mm version but works perfectly well on the 70ED, whose flattener is 3x the price for some reason) for £50 new.

@EJ22bakadesu 28 дней назад

A new Ed Ting video, a good way to end the weekend! I've always wondered how to pronounce that brand name. I usually just say "sivbony." I've been looking at their 80mm ED because it can often be had below $400 on sale but I need another refractor like I need a hole in the head!

@SolarityTechnology 28 дней назад

To be honest, I was wondering if Ed would ever touch a svbony. I got the sv503 102mm and really like it. Their support seems pretty good as we bought batinov masks and thought the 120mm one would fit, though it was to small. They sent us larger ones that fit our scope without charge. They were very responsive in emails.

@ducatifriedrich2910 27 дней назад

Thanks Ed. Just ordered, there was a $50 coupon so a great deal. I have an AP110 which was so expensive I baby it and use that for photos, this SVBONY will be great for quick grab and go visual. You didn't mention comets and star clusters, but I bet it will be good for them too.

@allancopland1768 27 дней назад

Another good unbiased review ED. A great pity the factory didn't spend a little time setting up the focuser correctly, because that could really put off newbies to the hobby and those tube clamps are a bit weird. For the price though it has to be considered passable. I have the SVBONY SV503 80ED and I'm very happy with it. Chroma drives me nuts, especially when viewing the moon's limb, but the 80mm SV503ED is pretty good in that respect. The 503 80 ED uses a different focus mount and mine was buttery-smooth perfection. straight out of the box. You may want to review some of the other SVBONY products, like their budget Plossls. I have a couple of low power ones and really like them. You are spot on about the importance of using a decent mount. I can be argued that the mount is actually more important than the scope. Wobbly mounts are a real hobby-killer.

@lesgatechair3907 28 дней назад

Hi Ed, and thanks for all you do here! I want to warn your viewers that if they look for a used version of the SV48 they may find a very different scope. I was an early buyer of the SV48 (NOTE no "P") about 4 years ago. Interesting, that the price then was also about $200 US$. Key things that were different were different ring set, focuser and adapters. I bought it to use as a better guide scope for my RC6, & switched out the rings. I found it to be a great guide scope over the years giving much better stars than 3 other guide scopes I have used. The focuser back then was a feather touch like 2 speed system (no gear, just friction). With tension adjustments I liked the feel of that system for visual but it was a big problem when I tried to use it for imaging. I couldn't get enough tension in the focuser so that the focus tube would not slide out when scope was pointing high. I took the focuser apart to add filing lines to the friction surfaces which helped some. Lenses may be the same, as I got very purple stars back then exactly as you describe, but not the distorted bright stars you showd here. The attachment adapters were low quality without the rings to prevent scratches on the 1.25" tubes. I think it had only single tension screws. It gave me 4 good years of use guiding but not much for imaging. Keep up the great work. I recently got an AT60 ED largely influenced by your reviews of AstroTech.

@edting 28 дней назад

Thanks for the clarification and info!

@johnrobison1413 20 дней назад

Thanks for that review. Not considering this one as I already have an AT 80ED but interesting to hear about what a fast achromatic lens can do. My current fascination is a short tube 70mm x 400mm picked up a year ago for $39! They have went up, now $77, but I am amazed at what this little refractor can do visually. It is from Spectrum Optical Instruments and the two refractors I bought from them on a whim (and because they were dirt cheap) have turned in a good performance. The all plastic focuser has top runner adjustment and I was able to reduce any wobble to zero. Focus is smooth and lash free now. A 70 won’t show what a 90 will, but since the OTA 1.5 lbs. it has become my ‘glove box’ telescope.

@marcusa3177 28 дней назад

funny enough - Svbony just released their take on that Vixen Porta and it's *really* tempting me for the nights where you don't want to break out your big equatorial mount and you just want to look at the moon, the planets, and the usual DSO suspects and soak up on all that night views.

@philippatroniti597 28 дней назад

I bought this lightly used on eBay for $6 + $24 for shipping on offer from a company selling it used along with an SVBony 1.25” dielectric diagonal and a generic 2x Barlow, 40mm, 32mm, and 6.3mm Plössl eyepieces. I got a MAJOR deal. The focuser is decent after spending a few hours getting it tuned properly. The tube is solidly built. The optics are a bit sloppy photographically, as shown in Ed’s pictures. Visually, it looks pretty great for an f/5.5 90mm scope. It has a strong split in the colors, showing a lot of yellow-green and blue separation when out of focus, but in focus it’s actually quite good. High magnification is a bit less sharp, but as a wide-field scope, it shows starscapes beautifully. It’s like a mini version of my Orion ST120. The focuser, once tuned, is similar to my Astro-Tech AT115EDT - just a bit stickier on coarse focus. You just have to make VERY small adjustments to get it smooth. I’d recommend a small amount of white lithium grease on the focus track.

@edting 28 дней назад

Thanks for the report!

@OzSteve 28 дней назад

Great review Ed. I bought one of these and was really disappointed in it (Here in Australia it wasn't as cheap) I managed to get the focuser nice and smooth but the optics really let it down (my short tube 80 was actually better) I ended up sending it back and at that time the Celestron C5 was on sale for $80 more than I paid for the 48P and I am impressed with the C5 for the money. I do want to replace the short tube 80 that sits on my 12" LX850. I'll look into the Askar range I think

@lixiaoyu1067 28 дней назад

Great review! I wonder how they could keep the cost so low. I have many Svbony products including their eyepieces, diagonals and their 102ed etc. and everytime I look at those all I can say is that I never felt like they are great, but they REALLY worth the money. Very interesting marketing and pricing strategy.

@user-lt9py2pu6u 28 дней назад

For the price it looks a good buy. I bought one of their 7n SII 2" filters and can't fault it for the money, also bought one of their dew heater straps for my 135 f2 lens, cost no more than other similar rated straps but included a simple controller as well.

@MikamisHouse 11 дней назад

Pretty cool and not expensive at all!

@rbrickproductions123 28 дней назад

SVBony is a great budget brand, especially if you’re an astrophotographer shooting in narrowband. I know someone in Dubai who is using this scope with paired with a Daystar Quark for a budget 90mm Ha solar scope & he gets amazing images. I used their SV503 80mm doublet w/ reducer & got some of my best images out of it! Excellent quality for the price!

@AmatureAstronomer 28 дней назад

I considered buying one of these, but bought an SvBony 80mm ED, instead. As for other refractors, I found that the SvBony 231 color correction filter combined with a Sharp Cap color correction feature cuts a small portion of the purple spectrum and changes the rest of the chromatic aberration into another color on my Skyoptikst short tube 90mm producing the same photograph as the SvBony 80mm ED. This arrangement even makes photos taken by my Bresser 102/460 look nice. As for the Orion Observer 134mm Newtonian, it is very nice, but I gave mine to a friend and replaced it with an Orion 130mm Spaceprobe, because the latter allows me to attach an SvBony 705c (asi585) or SvBony 405cc (asi294) camera without using a Barlow lens to achieve focus. As for the mount, I use a Celestron CG-4 mount with an attached Astro-Gadget go to conversion kit for my Newtonians and my SCT and a Sky-Watcher Star Adventurer for my refractors.

@nighttrain1236 28 дней назад

I got the Svbony SV503 (80F7). I can't complain for the price (on sale) although I've only had it out a couple of times due to the constant cloud cover.

@testboga5991 28 дней назад

Any scope with significant amount of longitudinal chromatic abberation is either a cheap visual scope or completely outdated. Purple fringing filters, wtf, it's 2024!

@AmatureAstronomer 28 дней назад

@@testboga5991 "...significant amount of longitudinal chromatic aberration..." Not all can afford a triplet APO. "...Purple fringing filters..." I have tried several and until I tried the SvBony 231 was not satisfied, as they reduced too much light and produced a color cast. But, this "purple fringe filter" combined with the Sharp Cap color correction routine APO quality photos for a fraction of the cost. I like doublet refractors, as they are light grab and go optical tubes, easy to use and inexpensive. Each to his own.

@marcgravel2382 28 дней назад

When I was looking for a unit to piggyback on my CPC1100, I went with the Svbony 80mm SV503 ED. Love it.

@kellytaylor3915 28 дней назад

I think the semiapo filters should be tried and a UV/IR filter on any achromat refractor. However the SVBONY 503 with 102mm scope is a huge bargain . Then the SVBONY 550 at 102mm is also a great bargain. At the price of the 90mm Ach it might not be perfect. The price point very good. I will be looking at SVBONY’s Best Spotting Scopes.

@BlueTrane2028 28 дней назад

I have a nice dual speed Crayford installed into an older 102mm f/5 achromat, Celestron "Wide Field Spotting Scope." I think I paid more for the focuser than the rest of the scope including rings. As I have it equipped, It's a decent casual scope, can look at a little bit of everything so long as you can get along with some CA. This 90mm f/5.5 looks in some ways better and some ways worse than mine, so I think I'll stick with the 102mm f/5. Nice review as always, thanks!

@DK-df2hi 26 дней назад

Ed - I appreciate your videos and you have a first class intellect. I was wondering if you could do a review of astronomy observing chairs. Mine sinks into the grass near my house and isn't very adjustable so I'm in the market to make things more comfortable and since I'm a heavy guy my choices are rather limiting. Even tough you might not cover my limitations I would be curious what you look for in an astronomy observing chair. Thanks

@KingLoopie1 27 дней назад

I wish these inexpensive telescopes were around when I started. You could buy 2 and join them to make a binocular telescope for pretty cheap with some blocks of wood and a couple more diagonals. Probably be a nightmare to collimate unless you built in the adjustments but something to play with if you like fiddling...

@AaronDalton1 28 дней назад

Awesome fair review of a low budget scope. Ed, you signed up for an Amazon credit card to get that $100 off, it wasn't a SVBONY sale. It's a $300 scope. 😅 Looks like there's some eBay storefront sales closer to $215 actually.

@petelopez5826 28 дней назад

I have one of these svbony scopes and I love my svbony sv48P. You just have to play with the 6 adjustment screws that you were adjusting earlier. I put some bar soap on my tube and this thing smooth as butter and it holds it weight pretty good. With the right filters you can get rid of the apochromatic abberation. Most of us can’t afford these high dollar apo refractors.

@mitrovarr 28 дней назад

@@petelopez5826 You can't fix chromatic aberration with a filter. Even if you get an expensive filter, that light is still gone, and the image still worse than it should be. It's also worth considering there are semi-apochromatic scopes for as little as $400-ish, with Astro-Tech AT80ED.

@chrimony 28 дней назад

Instant-off coupons are quite common these days.

@gabeeg 28 дней назад

Considering the price, well done SVbony. The only thing that bothered me enough to not consider this telescope is the flaring on the bright stars in the photos. I am guessing that is the result of the possible pinched optics that Ed mentioned. I did not see anything in the brief view that showed the cell is adjustable in any way. Other than that this looks like a nice intro scope. If there are any owners in here...can the lens cell be tweaked?

@Astro_Ape 28 дней назад

I still consider the EDL series from Astro-Tech to be the budget king. I have the AT102EDL & AT125EDL, both have been DPAC tested and preformed amazingly well. The AT102EDL was purchased new from Astronomics for $999!! A 4" doublet using a FCD100 ED element and lanthanum mate, with a fantastic 2.5" R&P rotating focuser, that has a .95 Strehl guarantee... delivered to my front door for under $1000 USD!! (Sales price for the 102 is $999 while normal price is $1199, but Astronomics had Astro-Tech sales fairly often) EDIT: OK, my bad. I should've watched the video before commenting 😂 I just heard you say that this scope was delivered for $199, which is a magnitude cheaper than the scope I was suggesting....

@MrTassadit 28 дней назад

he speaks about a telescope that cost 200$, can you consider that you are not fair to compare it with 5/6x mores expansive scope ? (fair or stupid)

@GrnXnham 28 дней назад

Actually, not a bad comparison would be Ed's $300 scope to the $419 dollar 80mm F/7 ED refractor by Astrotech. The Astrotech has a MUCH better focuser plus it being ED, has less CA. And it's not unreasonable to compare a $300 scope with a $419 scope.

@Neanderthal75 28 дней назад

I have the Svbony SV550- the 80mm triplet which really meant for astrophotography, but how says it can't be used for visual right? That's one excellent scope I can't find any fault to it, beside that it's only available with a 1X field flattener, no reducer. I did not own any other triplets so far, but I find zero issues with it, stars are round and no wrong colors, no haloes, no chromatic aberration, nothing. Fantastic. And yes, the focuser is better too, pretty much the same you'd find on an William Optics or Sharpstar telescope.

@oninoyakamo 28 дней назад

Hey Ed, years ago you suggested the Nagler Zoom was a good combo with the FS-60. I use Svbony’s 3-8mm Zoom with mIne. I’d be interested in hearing if you’d find the extra 2mm worth, what I can only assume would be, a dip in optical quality, if you ever come across one

@edting 28 дней назад

The issue isn't so much the eyepiece, it's the drastic increase in chromatic aberration that will start to annoy you. The 3-8 should be fine otherwise.

@confidentstreetlamp1762 26 дней назад

Hello, do you think the skywatcher evostar 90/660 as pronto would have good optics (better than an st80)? It is hard to find information about this scope.

@edting 26 дней назад

I haven't seen that one. There are tons of models out there I haven't seen yet! I'd be inclined to think it's better than an ST80 only because of its longer f/ratio.

@FatherTedCrilly 28 дней назад

I've owned my SV48P for a bit over a year now and it is a VERY fun scope. It can resolve 6 members of the trapezium on a good night of seeing. The focuser is a bit weak under heavy loads, but for ~$250 USD I can deal. There was no play in my focuser, but I did collimate it with the 120* set screws. It excels at open clusters.

@OMMgreenshirt 25 дней назад

Svbony does have equipment beyond the "department store telescopes". I am skeptical with so many knock off telescopes coming out of the far east but is it possible for the amateur astronomer watching their pocket book, that there is a new sheriff in town for options to consider getting into astronomy?

@RT65CB-SWL 27 дней назад

If Svbony get their marketing and QA right, they may become the biggest threat to the likes of Celestron, Meade, TeleVue and others in the amateur astronomy community😮 They have certainly proved a point with the release of the SV215 3-8mm zoom. It would make an interesting video if Ed did a comparison of the TV 3-6mm and the SV 3-8mm. I have one of each and no regrets in buying either😊

@MountainFisher 27 дней назад

Do you know what causes those spiky stars? Cheap glass polishing and I find it an issue with their zoom eyepiece. Even my cheap Celestron Zoom didn't give me spiky stars.

@edting 25 дней назад

Those controllers are becoming very hard to find. I assume you've tried the usual places? Astromart, Cloudy Nights, etc. If you can't find one, you might wind up deforking the OTA and putting it on a plate for an eq mount.

@h.n.4060 28 дней назад

I have been testing out older versions of this same scope just a few days ago, one made (branded) by a company called 'Aqulia", the other by svbony. I really want to know what causes those "harry" looking bright stars, as both models have them, and it's sad to see the new version still has it too. It makes some targets totally impossible to image (though I didn't really notice them visually). I assume it's pinched optics as well as a screw or something in the light path, but I can't figure out how to loosen the lens cell to see if that would fix it. If it were fixable, a telescope like this would probably be perfect for narrow band imaging.

@lesgatechair3907 28 дней назад

@@lesgatechair3907 That's very interesting. Nebula Photos also used the telescope (The same as the one I, and I assume you, have. See the video '4 Telescopes Tested from $300 to $2300'), and it looks like the "hairs" are not as present there too (that said his image of M101 looks very similar to mine, but bright stars, like in the Pleiades, make it totally impossible to get a good image, it ends up looking more similar to what Ed shared). I didn't have any problems with the focuser on either telescope, the Crayford focusers on both were able to hold a mono camera + filter wheel without any problems.

@mitrovarr 28 дней назад

One thing I'd add about the "using a photographic tripod with a telescope" issue. You can't really save money by buying a photographic tripod for use with a telescope. Can you use a photographic tripod with a telescope in some situations? Sure. But it has to be a relatively decent one - you can't use a really cheap one designed for smartphones or old point and shoot digitals. It has to be a nice, big, serious one meant for using SLRs with potentially heavy lenses, or maybe large binoculars. Those are not cheaper than the least expensive decent telescope mounts, like the Twilight I. So you can only save money in this way if you already own one, and for that you'd have to be a fairly serious photographer. Unless you spent at least $150-200 on your photographic tripod and tripod head, it isn't even worth trying with a telescope, particularly not one of this size and weight. Just buy a telescope mount.

@jorymil 26 дней назад

Video tripods are sometimes better in this respect: they usually come with fluid heads, an easy leveling mechanism, and double-tube legs for some extra stiffness. And no center column! I got lucky and found one for $10 at a thrift store; it works great for scopes of this size.

Begging the question of why anybody would do this, if you've got $2k to spend on a mount and tripod and all the other cash burning a hole in your pocket to spend on the other accessories and gizmos why not just buy even a budget apochromat?

It's a fast achromat. It has the same color correction as all of them that aperture and speed.

You're shooting the current messenger/brand, when the message has been known and constant for centuries.
