M33 Triangulum Galaxy, about 3 million lightyears away, so... not that far. M33 is a relatively small spiral galaxy with only 40 billion stars. I'm having some trouble with my guide camera (ZWO ASI120MM), so this is all unguided. I took 80 LRGB exposures--120 seconds each, 10 Ha frames at 120 secs, 20 dark calibration frames, stacked in DSS).
