Has anybody used this OAG? I can get the M54 or M68 version of it for $108 with free shipping from a seemingly legit store on aliexpress right now. To this point I've been using an 80mm guide scope with flexure correction on my C8 and it's worked totally fine, but now that I have a 102 triplet I'd like to get an OAG for the C8 and use the 80mm on the 102. This is basically half the price of other OAGs I've seen so obviously is of interest. Link below, I know stuff like prism size matters a lot so I just don't know here, I've never really dove into off axis guiding before.

Looks like a great price and has a very nice large prism, should work for pretty much any setup. The 17.5mm thickness is great for just about any filter drawer or filter wheel if you plan on adding one of those in the future also (touptek makes both).

I use my oag setup with all of my scopes, Askar 400, 122mm refractor, and c9.25. About the only reason I would ever use a guidescope again is if I'm using a hyperstar or rasa.

Currently having fun figuring out how to install it alongside a filter wheel. Looks like it all needs to be done in a particular order and the manual is no help!
