This is NGC 7008, the Fetus Nebula, captured using narrowband and presented here in the Hubble Palette (SHO):

This image is a result of 120 minutes of total exposure time across all narrowband filters (HSO). I processed this image using PixInsight. I had some problems processing this image because the nebula was very faint, so I processed it manually after integrating the images using AutoIntegrate.js. I focused my efforts on stretching the image to get the most out of it and then used AutoIntegrate.js to perform final edits like reducing noise.
