I wanted to mount a Solarscope Solarview 50 on an old Celestron SLT mount to use soely for solar viewing/imaging. The Solarview has a flat base plate so I needed a small Vixen type dovetail with a flat mounting surface, which this has. This dovetail is a solid pice of kit, which I screwed onto the mounting plate with two screws.. Because it has a slot along most of its length, the scope can be balanced to suit whatever is on it and it is also solid in the clamp.The only downside for me was that, as this dovetail is designed for mounting a camera, it came with only one mounting screw, which unfortunately was too short for my application. However, a pack of two longer screws can be bought off the website.
