This BUDGET f4.5 refractor TROUNCES the RedCat 51! SVBony SV555 FULL REVIEW!

20241218: Update video on the backfocus situation:    • ⚠️SVBony SV555: Backfocus considerations/l...  

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!
