This scope looks like the same as the AT80EDT, however, there's a 0.8x reducer flattener available for the AT80EDT, whereas for the SV550 80mm triplet there's only a 1x flattener, and svbony advises against using reducers, as they could degrade image quality (I read it on their webpage). So, maybe they're not the same? I know Ed Ting reviewed the at80edt and found it to be excellent, a nice upgrade for eg the orion ed80.
Great review I'm sure you could get a flattener to work with it ok I've done the same with my Altair 102 EDR by using the SVBony flattener. If you're thinking about imaging with a faster scope beware as they can be frustrating as well as rewarding. I've got a RASA 11 V1 & when its dialled in its insane but if something is off it will show up in your images like a sore thumb lol.
Great! I've been debating for getting a longer focal length refractor or a triplet, but I sort of lean towards the doublet, the Svbony 102mm has a very attractive price point for what it is, and with a mono camera the doublet will just work fine. I have the svbony 80mm already, which works just great with the mono setup. But I'm curious about 102mm, because I don't have one. Also if you want something faster, but don't want to spend a boat load of money on a new scope, why don't you try the Starizona Apex AD reducer? Granted, you loose more focal length, but if you're ready to trade focal length for speed, then there it is.
Most astro targets are really big. I just finished one target that is 6 degrees across. That is like lining up 24 full moons edge to edge. So focal length is not an issue. My next imagine rig will have a 135mm fl and even that seams long. The Starizona Reducer would probably tempt me if I did end up getting this scope.
@@OzSteve I found out why in one of his other videos. It's an achromat, not an APO and since he only does Narrowband work with it, color fringes don't matter. It would not work with a one-shot-color like the ASI533 or my ASI183.
I am pretty sure I put photos taken with this scope in my instagram and also in another video about it. The 503 is not perfect optically like this scope. It has some Chromatic adoration issues but those are only a problem with OSC cameras and since every camera I have but one is a Mono camera it is not an issue for me.
Hi, last week first time tested this Apo, was surprised with not flat field and stars trails from the corners, same cheap reflector. I use flattaner, zwo filter holder and asi294mn pro, am5 + guide . Did you meet that?
I was wondering too; it doesn't look like a ZWO camera, and afaik the ASIAIR doesn't support non-ZWO cameras. But if it does, I would be interested to see how it works.
For all the Money that Astro gear costs . Why is it that it's next to Impossible to achieve A Quality Single Capture . . than having to take multiple images to stack Why is that Astro Gear can't achieve it but if it can then why do Astrochannels never show it can be done
Good question. Its is because we are dealing with such faint objects. In astro we are dealing with much fainter light levels and huge contrast ratios that would make any daytime imaging process blush. Daytime imaging you will often see contrast level of only about 5 stops while in astro imaging 20stop contrast levels are the norm. So HDR which is sorta what we accomplish with image stacking is an absolute must.
