Vixen Mount for 152/900 Refractor

thingiverse

Since my TS Optics 152/900 Achromat doesn't come with a viewfinder mount, I decided to design one myself. To avoid attaching it to the eyepiece extension screws, I had to use the unused holes on the tube clamps instead. The contact surface isn't a perfect fit because I want to account for any inaccuracies from my 3D printer and I've also glued a piece of velour in place. For now, it's still a work in progress but it should fit okay in principle. It's designed specifically for the version with a 155mm tube diameter - if you have the 178mm version, this won't be compatible, but I'll make another one if mine works out. The TS Optics 152/900 Achromat goes by many names: Technosky, Nerius, Astro Professional, or Individual. As long as your telescope has a 155mm tube diameter, this holder should fit - you might need to make some adjustments due to different tube clamps. Update May 1st, 2020: I've reduced the distance between the holder and the tube by about 1mm to accommodate that piece of velour.
