Going to like this scope. 30 minutes, tons of tiny galaxies (zoom in, particularly to the left).

Subs are way overexposed. Maybe 10 sec at gain 0 would be best. Still things to learn about processing with this setup.

Redid the image, keeping it with this one for contrast. Lowered subexposure (compensated with more total imaging time), got a better night, processed better. Autoguided this time, see Pelican for details.
