Equipment Details:

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

Post-processing Details:

I processed the stars and the nebulosity separately in PixInsight and Photoshop, mostly just bring up the light on the nebulosity without blowing out the stars with excess light.

Image Details:

This is M45, the Pleiades. About 7 1/2 hours of total exposure time in 300-second images. I took about 90 images and stacked them. Some are from last night, some from the night before, and some were a couple of weeks old.
