Ekos on Raspberry PI Beginner's Guide by James Taylor #39341
I have to say the 2016 article was brilliant and an absolutely accurate guide in building your own observatory computerand when I made my attempt to duplicate your article all I had issue with was installing Astrometry but after reading the how-to I was able to install both the local and remote services. My build works just like the StellarMate I own. Literally everything works perfectly on both of my mounts. It's like having your cake and eating it too.
If a person has a laptop that isn't doing anything and you have an itch to build this is a worth while project that will give its user hours of fun and satisfaction.
