First of all, thanks to @Kaczorek for his work on Astroberry -- seems to be exactly what I need!
Now, a question: I'm preparing to test it on my local setup (Mallincam Micro-EX camera, a miriad of Celestron/Orion telescopes, and a Celestron AVX mount) but I only have an old Raspberry Pi Model B with 512MB RAM (
this one, to be precise
), and no easy/convenient way to get a Raspberry 3 or 4 as recommended (given the COVID-19 situation and the fact that I'm overseas).
