Review on SVBONY SV165 Mini Guide Scope 30mm F4 Finder Scope: Ideal for SV305 Pro, ZWO, QHY, and Orion Auto Guiding Cameras by Mirzet Gosselin

My biggest concern was it flopping on my mount - I've seen videos of people talking about the rails not being solid which makes aiming bad - That leads of course to them to buy more expensive rail sights which are tight - This scope is 100% tight when the adjuster is locked - It doesn't move a bit - I'm so impressed with this scope - I don't know how you can get a better product can for that price. I use one of those pink ASI120 clones sold here at Revain with the extension ring that comes with it so the camera can be a good distance from the lens - it only takes a few turns to set the scope so you don't over-extend the focus setting - it also helps keep the scope narrow. This combo gives me a premium Guide setup for less than $130.
