Finished up the polar mount.
I added a camera module from aliexpress as well as some final structural touches to complete the mount. I decided that for tensioning I am going to try the fight during assembly thing, but if that doesn’t work out then I do have an aluminum extrusion crossbar that I added that I could either use to add tensioning or use the mounting holes of to add tensioning. Either way there are options to solve my problem. Now, I move on to equatorial.
