20241218: Update video on the backfocus situation: https://www.youtube.com/watch?v=utwtIYVkUEk
20241216: there have been reports on CloudyNights of a samples that couldn't reach focus with the standard 55mm of back focus. I haven't had that issue, but I had inserted a UV/IR cut filter in the scope (and had it in throughout testing), which does shorten the backfocus. I have contacted SVBony about this.
The SVBony SV555 is a small telescope/lens with a 54mm aperture, 243mm focal length, and F4.5 focal ratio! Awesome to see such high performing alternatives to traditional scopes, especially with a (relatively) low price!
