The Crescent Nebula, NGC 6888, cropped from a narrow-band-one-shot-color, NB-OSC, Hydrogen alpha and Oxygen 3 image with 4 hours total exposure taken with WO RedCat 250/51mm scope, ZWO ASI533 MC camera, ASIAIR controller, PixInsight with GHS and RC-Astro Noise/Blur/StarXTerminator plugins, PS for final exposure and crop.
This Eagle Nebula, M 16, with the Pillars of Creation was my long exposure summer project for this summer. Over 24 hours of total exposure captured over 11 nights. Captured in 290 five minute narrow-band one-shot-color images. My goal was to show both the faint nebulosity around the eagle as well as detail in the bright pillars region in the center.
