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.

      The lens is the telescope in this case. But as the focal length of 135mm is fairly short it works best for objects appearing very large in the sky. Astrophotography can get very expensive very quickly, so we try to make the most out of the equipment we have. Just like with the 3d printed mount.

        I’ll have to check out the lens more, out of curiosity. I’m sure astrophotography had all types of trucks of its own. I have a 300mm 2.8 lens and no way is it zoomed in enough to get that nice photo you have of a nebula.

          I can recommend this online telescope simulator where you can simulate the field of view with your equipment. Your 300mm lens should be absolutely perfect

          The full moon is about 31 arc minutes in apparent size. Andromeda is about 190 arc minutes in apparent size. Based on my Eclipse photos at 700mm, the biggest issue you’re likely to have with the 300 f/2.8 is picking what part of Andromeda you want to fit in your photo.
