NGC 6781

This is a little-known planetary nebula in Aquila called NGC6781. I've been doing astrophotography for six years and I only just figured out that it exists. This is a stack of 101 300-second images, taken over the nights of the 28th and 29th.

StellarVue 152mm refractor, Nikon D810A DSLR camera, Astro-Physics Mach2GTO tracking mount.

Separated stars from nebulosity, stretched the planetary nebula a little, stars hardly at all. Recombined. Sharpened slightly.
