Crescent Nebula Photographed on 9/17/2016

This is  the Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105).   On this night, I captured 31 raw images with my Nikon D5300.  Each exposure was 150 seconds with an ISO level of 1600.  I used a Baader Nebula filter which helped drown out a lot of light pollution and added contrast to the nebula.  For calibration frames, I created 20 darks, 20 bias, and 20 flats (exposure .10).

  1. I was reading your article and wondered if you had considered creating an ebook on this subject. Your writing would sell it fast. You have a lot of writing talent.
