I know a lot of astro stuff makes use of serial connections, especially the older ones. I figured this would be up someones street! https://hackaday.com/2021/04/18/diy-wireless-serial-adapter-speaks-true-rs-232/

Just to chime in on this, I use a Baader Zoom and have it wide open (24mm) when using go-to and aligning. For the actual alignment stars I then zoom it right into 8mm and get it as optically centered as I can. It's no crosshair, but it's done well. I had M13 mostly-centered in a 102 Startravel for upwards of 30 mins (just looked like a smudge, but for visitors it was a good comparison with the 10" dob set up next to it), and then was quite happy swinging round to other targets. The other targets were usually slightly off, but I could always find them at 24mm, get them re-centered and mark it aligned on the app. After that the tracking was fine.
