SVBONY 122mm APO Astrophotography Review 

+1 on this, Ben!

Much appreciated

Thank you!

You bring up something I should have mentioned in this video. The cost relative to their 80mm. While this scope is twice the size it is not 3x the price. And interesting fact that SVBONY was able to scale this one up without massive increase. However the rule for most refractors is still a reality. Larger exponentially increase the price. Though they're 80 and 122mm compared to each other seam to be an exception.

@@TheNarrowbandChannel Oh! That's interesting!🤔I wonder if the smaller than expected price difference is due to (a) really large volumes produced for the most common sizes of apo lenses made by Chinese manufacturers, (b) the availability of the grades of glass blanks they use for 80mm and 122mm lenses are the same, (c) the fact that machine grinding/polishing (and touch-ups if they do that) plus coating of 80mm and 122mm lenses are both quick & easy, plus (d) assembly, collimation, and construction of the tube assembly for 80mm and 122mm are also very similar.🤔

@@derekbaker3279 The company that makes the SVBONY ED doublets and ED Triplets is the same one that makes other high-end refractors. The SV550 80mm and 122mm have the same focuser as the Stellarvue SV70T Triplet (and some other SV models). The SV550 80mm does not have the rotating focuser which is the same as the SV70T. You need to buy the CAA if you want to rotate your imager. I own the SV550 80mm and 122mm as well as an SV70T focuser so I know what I am talking about. What helps the SVBONY Triplets price-wise is the center lens element is FPL-51 and the other two Lanthanum. And at a native F/7 it is perfectly fine and right up there with FPL-53 and FDC-100 glass types. However where the latter types come into play are for the shorter F/R scopes which better controls the spurious color. At F/6 and faster, you would want the FPL-53 and FDC-100 as long as the workmanship on the lenses is top notch. I have looked through many with FPL-53/FDC-100 and nearly all showed color visually. Very little, but still there so even the "better" glasses don't always help. This SV550 122mm has zero color because it is F/7 and fine workmanship. They literally hit it out of the park with this 122mm Triplet. Some optician found the key to make this glass combination work! The right figure, and the right spacing. BTW, the same manufacturer also makes the Astro-Tech scopes and many others. Price differences are because of the "options" the brands want at the time of ordering.

@@derekbaker3279 Could be some or all of those.

I appreciate that! Some days the only thing I have strength for is editing these videos.

You rock too! Love that hat. I can make up all sorts of wild stories and people fall for them. Lol

Thank you and enjoy that big APO!

Well said! A C11 is a lot of scope too!

I appreciate that!

Me too!

Thank you Jeff!

Thank you! You too!

Wow, thank you! 140PH is a big boy. RASA scare me a bit though with allll the calibration. But maybe it's not that bad. After all I find calibrating a newtonian easy.

Glad you like them!

Feathertouch is probably about the best focuser you can get.

Its not hard but requires precision. This one though is so close.

Glad you enjoyed it

Its a great buy

@@TheNarrowbandChannel Thanks. I always get a bit of anxiety after splurging these amounts of money, but there we are. Looking forward to using it!

Many thanks!

Glad it was helpful!

In the city they were rare but in the country they are just everywhere. You can't walk very far without physically colliding with one.

Here is to another big APO :)

Ya I found that music online. The composer wrote it for a video game and last minute the game company went with other music so he made it open source. Shame on them cause it's a good soundtrack.

You bet Joe!

I love shots ASKAR scopes too. The 260 RC is one I drool over often. Maybe someday when I have a permanent observatory.

I looked at the specks and both scopes are the same weight you just gave I think 8% more light with the larger scope.

Great to hear!

You and me both!

Thanks man. They reduced my dose so its going better this round.

You are so welcome!

Very true with them too.

Very nice!

Thanks Jeff. ZWO is sending me another ASIAIR Plus soon. The new one to test and use. I'll probably buy it but first I am waiting to see what my CT scan looks like next week.

Thanks for subbing! yes those are fire flies. In the country they still exist. But city light kill them.

@@TheNarrowbandChannel I have been to country skies as well portal zone, two right average of 6to 7 times a year and I still don’t see them It could be a particular time as well, like in spring or fall or weather

Totally agree

Awesome! Thank you!

Its a great #2

Thank you for your prayers Rich. I think they are working. Will know soon. Yes i to like the filter. Been using it more and more. I still prefer the flexibility of my mono cameras though.

Thank you12Astro!

It's so minor though. I am tempted to leave well enough alone.

Tilt should be done on the camera.

Have you check our my 120mm achro scope video? I did it i think two years ago. Saved me like 2600$ over getting a triplet.

@@TheNarrowbandChannel haven't seen that one yet, might need to find it later and watch it. Astro may not be cheap but there are Definitely ways to make it way cheaper.

Thank you brother.

Hi Kevin. The rotator now has degree markings on it which I think is actually pretty cool however I still prefer to rotate the entire tube. If you do want it though I would put the rotator between the reducer and the scope this way back focus is not affected and if its nice and straight should minimize the need to redo flats. About the weight. It is a heavier scope but considering the entire weight of your current rig it would not had a huge amount. Best wishes to you with your chemo and immuno therapy. The tell me that process is a good one. Much easier to recover from than my FOLFOX Chemo I am on.

Thanks very much for your reply!

Someone else asked the same thing. It's the same but you het a little more aperture and a much better focuser. 8% more light.

Yes I have used them. Waist of money I think. A touch soft is actually beneficial to guiding anyway.

Very good to know! I saw them earlier and was wondering.

Thankyou! What part? Russia is so huge. My college roommate was from mosco

Probably a 60mm guid scope.

They are air spaced.

I did a separate video for visual observing on the channel

Last night i was averaging rms of 0.37” and worse nights are no worse then 0.77”

@@TheNarrowbandChannel Nice! I’m so looking forward to getting one in the near future.

@@TheNarrowbandChannelis that with the 40mm guide scope?

@@WilliFromEarth No I am using the DUO so its guiding at 680mm through the narrowband filter.

@@TheNarrowbandChannel Thanks!

TS rules the euro market.

@@TheNarrowbandChannel it's also one of the few good options in terms of price, stuff like William optics is super expensive. Same goes for other equipment too, cameras go from 200€ more expensive on the 533mc to 1k for the 2600mc

Maybe it's not that expensive on the official website，hah.

very true. @@fenice319

@@Svbony I took the price from your own website, it's around 300€ more expensive than the ts counterpart

Now that I think about it, I've only ever seen people throw out subs due to vibration or clouds. I throw out subs that are completely blown out from some giant yellow streak going across my frame like a supernova.

I know ;) cant wait to get the mono version and. Afulll filter wheel. Sho ans lrgb.
