Using a camera lens and a ZWO ASI camera

After looking online at 3D printed items for Astrophotography, I decided to design my own system for my application. First, I had to draw in 2D, since I am an Ole school Architect, taking measurements and thinking about how things line up which took about 4-hours of measuring, drafting, dimensioning and thinking. Then I ventured into the 3D design drawing which took me about 3 hours. I have to look at UA-cam videos a lot when doing 3D design. I have my own 2013 Revit CAD program that I did both the 2D drafting and 3D modeling in. Now I can use my old film camera lens that has manual f-stop settings at different zoom distances. But mostly it will be set to f/4.
