M31 Andromeda Galaxy
Taken through my 15" f/4, Paracorr, Canon R5ii. 200 x 20s exposures at ISO800. First light since I cobbled together auto tracking on my single axis equatorial mount with a custom mount controller box (just on a breadboard while I wait for the PCB from Oshpark), a finder scope and tracking camera feeding PHB2 on a Raspberry Pi, and custom software converting PHB2's event stream into Bluetooth messages to the controller box and polar alignment instructions delivered through a custom web interface on the Pi's hotspot.
I'm still figuring out stacking and stretching, but I'm happy with the level of detail here. Drift in declination (which is untracked) means I can't have really long subs, but my next project is motorizing the southern feet on the platform to get 2 axis tracking (at least, in most of the sky). Then I'll really be cooking.
