The last telescope you will ever need to buy - Svbony SV550 122mm Full Review 

@cattaraugustonawanda4426 Congratulations on your new telescope! Let me know how you like it once you get to test it. Svbony told me soon after the review that they would release a handle bar for the SV550 122 soon. Clear skies!

@BurningFlame1999 Thanks! For visual the 102 Bresser should be the better choice. The larger aperture will catch more light and the longer focal length will eliminate a lot of the chromatic aberrations and also be more forgiving on the eyepieces.

@@BogdanDamian Thank you a lot for the answer :)

Hadley 114mm/900mm

The specifications are almost identical, the main difference being the aperture 122 vs 127 mm. I guess the image quality would be almost identical too, the 127 mm triplet images would be a little just a little brighter.

@3dfxvoodoocards6 Like with everything else, a telescope upgrade obeys the rule of diminishing returns. To get that last 10-20% of optical performance you need to pay up progressively more the closer you want to get to 100% (perfect). The 122 is definitely not 3x times as good as the 102, but if you are looking for a bit of improvement, then there is no way around paying it's price. Where the 122 shines, though, is when comparing it with other similar telescopes. In this scenario I believe it offers one of the best price/performance ratio on the market today and is definitely worth it's asking price.

@TheNarrowbandChannel Thanks for letting me know! Then it's only my unit so far with this problem.

@enriquejesu4512 Hey! It's not the 16", but I do have a review of the 12". The Prodob series is great and if you don't mind the size and weight, then the 16" will make for an awesome telescope. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-loPpFGP-Sgc.html

@@BogdanDamian thanks for the quick response and insight! There’s really no review on the 16 in telescope from the prodob series and the price I see for it sounded a little too good to be true, but asking someone who owns a telescope from the same series give me less doubt about its optics and overall performance. Again thanks for your quick response👍 clear skies!

@vince953 If you are happy with your Dob, then keep it. Dobs are incredible versatile and can be modded to improve the performance very easy. If, however, you want to experience something new/different and size and price is no object, than a 5" - 6" f7-f10 APO refractor would be worth checking out.

@MountainFisher The idea with a Barlow lens without a lens as an extension tube would work as well. I guess I never thought of building my own handle bar, thanks for the tip.

@@BogdanDamian You can make an even simpler handle by cutting a 13mmx30mm board just long enough to fit across your scope rings and cut two more pieces 25mm long and glue them on the ends of the handle. Then measure and mark holes to drill out and put bolts through and bolt the handle to the rings through the handle with the blocks underneath. Just file the ends to smooth them out, paint to match your scope and re-attach.

@WilliamBlakers Thanks, it's definitely something I will keep in mind for future reviews.

@michaelklemm-abraham7298 That is correct, the first and third objective element are made out of a different types of glass than the middle one. Both contain Lanthanum(III) oxide among other elements. Unfortunately Svbony didn't specify which ones these are.

Saved me the trouble😮 of posting the same ? ❤

SvBony always use the cheaper FPL51.

Clearly, visual performance must be the most important parameter when assessing a telescopes performance whether visual or astrophotography.

@bitslizer That is great!

@kamilmoucka6811 I love my 12" dob as well, but in terms of sharpness it can't keep up with a premium refractor like this one. It allows for higher magnifications and brighter views though. There are always tradeoffs I guess 🙂

@@BogdanDamian I agree with that, of course. I still remember the little 56/540mm Carl Zeiss Jena triplet refractor from the former East Germany that I owned 40 years ago. The pictures of the moon and the planets were simply amazing. But to resolve the tighter binaries and more detail on the planets the tribute was lacking.😄

@ishanar8697 Compared to my 4" SkyMax Mak and my 12" Prodob, the sv550 delivers significant sharper views. The sv550 is also brighter than the Mak but not the Dob (makes sense given the aperture difference). Contrast-wise the sv550 is roughly on par with the other two. Hope this helps

@@BogdanDamian Thanks for the reply, I'm sure it's a superior scope to my Mak and for the price it really should be! One day maybe...

​@@BogdanDamiancontrast SIGNIFICANTLY better than ANY obstructed system OR it should be.

How did you get the bino viewers to work on you dob? I have a 10" bresser and was looking at forums and people were saying it's extremely hard to get bino viewers working on a dob something to do with focal length

I was looking at the max Bright 2 bino viewers

@anandarochisha Sorry to hear about your old scopes, but the 24" Cassegrain sounds really awesome! Love to hear some details on it when you got the time.

Congratulations on the divorce, and the new scope. Two birds, one stone. Clear skies!

@@gooe9561 thank you..I saved my soul on that deal. Love my Q3.5. The Cassegrain is going slow..it's a bit humongous in a bunch of ways. Have a great day..

It is funny what some people consider broke. A used questar is not in range of any truly broke person, unless the seller was a tweaker with a stolen Questar or a really uninformed person who got the price from a picture of an etx90 and thinking the Questar was one of those. So sir, you were never close to "broke", just "relatively broke" , losing HALF of an incredibly rich or at least super upper middle class (assuming half as the standard divorce situation), set of assets, having 2 large AP scopes, replacing them with a Questar (which is yes cheaper, but also costs as much as many 5" apos and the.cheapest 6" apos), and building a 24" anything and an.an observatory is no where near ANYONE in the real world's idea of "broke" This has been poked fun at in movies and sitcoms before, what the rich and sheltered consider suffering. I had encountered a girl from an Uber rich family, $50k a month allowance, no credit limit.card that daddy paid for etc... she thought her family wasn't rich because they didn't own a private jet... but I am sure their yacht(s) is(were) quite nice. Now my situation, never being truly rich but getting a taste if it at a young age with a low 6 figure trust fund, mostly.lost to.bad investments, and a mid 5 figure life insurance payout (also lost a good bit to poor financial management), finally going to work for an astro retailer after too many years as a professional community college student, and à freelancer in 2 of the fields (audio and photo). Still making in the low-mid 30k range, but being able to afford decent used astro gear that came through the store at a huge discount (10% over a similar amount a pawn shop would pay so we could sell at the going used rates), as well as when there was a sale or clearance. And then losing ALL of it to tweakers and not getting a dime from insurance since I had to put the storage in my mom's name because I was moving from a smaller unit in the same location and couldn't get the decent move in rate otherwise. That was being broke, as I had previously had a breakdown and was forced onto disability, not much hope of rebuilding after a total loss with no compensation, being on disability and having to hide on a boat since it was impossible to get live aboard in my part of the world, on an SSDI.check from.a.job that only paid $36k or so, even being the top salesman there, 1% gross commission without margins being taken into consideration, I was being robbed by them for years too . So naturally I had to keep everything in storage. And when I got.kicked out of the marina and facing van life until housing assistance kicked in, some.tweakers saw me loading in guitars and fishing rods, and 2 weeks later they hit the jackpot and got all of my music, pro audio and astronomy gear, and I had way more pro audio.gear than I did astronomy gear because I was planning on opening a studio ,.that never happened, but I had pretty much all of the gear except the large console, over years of collecting when i was still on the trust fund. Mt mic case alone was worth a nice solid imaging rig or more. I keep having periods of major bad luck where either some tweakers, or a corrupt city/county or impound yard, robs me and I get ZILCH in.compensation.

@danielbrowniel I asked myself the same question regarding whether the sv550 would make a decent solar scope. I might try this out in the future.

@@BogdanDamian Considering the expense of just an 80mm Lunt solar scope, it would be interesting to match that up against this. Mixing and matching parts scares the hell out of me when it comes to looking at the sun, I think I would be happy with a dedicated scope. It just sucks that what I really want cost 6 GRAND and there is no way in hell it is worth that much to me. I would go 3, but the solar scopes for 3 are not worth 3 to me, they are worth 1K.. Solar scopes break my heart.

​@@danielbrownielit sucks when your solarmax 60 gets stolen after you lost your position to both earn money and have access to astronomy gear deals

@whatmattersmost6725 According to my contact at Svbony they really designed this telescope themselves from the ground up. What factory ultimately made it, I don't know. But I agree, the scopes coming out of China right now are really good.

@@BogdanDamian I bet it's made by "KYO United Optics"

Is there any other company that sells the 122/854mm FPL51 triplet ? I don’t think so.

Sometimes a "name" partners to bring out a new product, with a chinese manufacturer. The problem with China is that intellectual property means dick to them. Give it a few years and it will be an astromania 122mm fpl51 triplet for 2/3 the cost. I highly doubt svbony owns an optics factory. They are definitely a rebrander. But when a rebrander gets popular and successful, the OEMs will start to build stuff for them to different spec. But the exclusive period can be quite short. That is why it is better to use taiwan or japan, like televue did.

@@3dfxvoodoocards6 What you may not understand when you contact say KYO and ask them can you make a 122 or make something different? There are scopes very close to the SV122, and fact I own this scope and optically it's very good for the money but the focuser is less quality then the glass. But for the $$ hard to beat..

@Alpamayo84 Hi! I'm polish, but I get asked this question often. Glad you enjoy my videos 🙂

The Svbony 122mm FPL51 triplet costs 1400$ now. For that amount of money you can at best get a 110 or 115mm FPL51 doublet or triplet made by other companies.

@@3dfxvoodoocards6 that price definitely is brutal.

I have the Svbony 102mm ED and I don’t have any problem with focusing. Everything works great. But who knows maybe other customers had that problem.

He didn’t make a salad with it either how will we know 😭

​@@G4L4CTICR4DIOhe has a point. 1/2 of the 2 main reasons for buying a triplet apo is imaging

@@k.h.1587 right. I was being snarky
