Triangulum Galaxy (M33)

ASI2600MM, 360mm f/2.8, 2.9h (3x 40min R/G/B, 1h Luminance)

The Triangulum Galaxy is just a bit further away compared to the Andromeda Galaxy but much smaller and not to observed with the naked eye. This picture is also only a crop of the original framing at a focal length of 360mm:.

M33 was one of my first light from the APO and the color camera. With just one hour of exposure time I captured the following image. Due to the higher optical magnification the crop has similar details, but it clearly suffers from the much shorter exposure time and slower optics:
