This is a great scope with auto focus up to 800mm. It's set up as explained by another user: 3 streams, front stream allows you to remove the lens, then front and back stream. The red ring is a retaining ring that prevents the sight from changing focus. My ASI290mm had to be exactly 45mm from the red ring when locking. The threads are very thin so it's easy to get perfect focus before fixing everything. The rings have soft grooves on the adjustment screws and you can easily rotate the camera in the rings. This guide has a finder mount rather than a dovetail mount. This is a very compact scope once set up. I can attach a 1.25" adapter to my camera to use a 1.25" UV/IR filter when aiming. I plan to pair this with RASA 8
