This is five hours of NGC 2238, the Rosette Nebula, with the open star cluster NGC 2244 in its center. I actually started shooting around 11:45, in 5-minute increments, and kept going until the sky got too light at 5:30-ish.

Stellarvue 80mm scope, Nikon D810A DSLR camera, Astro-Physics Mach2 tracking mount.

I processed the stars and the nebulosity separately in PixInsight and Photoshop, but didn't change much. Just brought up the light and the color.
