Equipment Details:

Stellarvue 152 refractor, Nikon D810A camera, Astro-Physics Mach2 tracking mount

Post-processing Details:

Processed the stars and nebulosity separately in PixInsight and Photoshop. Mostly just stretching for more detail.

Image Details:

This is M1, the Crab Nebula. I took it over two mornings, starting at midnight or 1:00 and shooting until 6:00. I actually gathered 118 (300-second) images, but in the stacking I found that only 80 made the cut. Sky conditions were iffy this morning. You can very faintly see the pulsar in the center of the Crab.
