I found this design and it fitted my need perfectly. It is a mount for a very popular camera lens used in astrophotography. It not only functions as a weight relief for the camera but also allows to rotate the field of view. Moreover it is possible to focus the lens with the installation of a stepper motor, which will be the next step.
The single parts are screwed together with the help of threaded heat inserts. Just to make sure they are also glued together with epoxy, as the mount really needs to hold up. The screws are locked with Loctite.

Thank you! Andromeda is way bigger than most people think. That’s the reason why it is a very (maybe the most) popular target for beginners. Also there went a lot of processing into the image, so don’t let the image deceive you from the actual conditions where I live (Bortle 5 zone)
