Sharpless 216 - Second Closest Planetary To Earth
This is one of my longest images because the object is very faint.   I used CCD Stack to process the H-ALpha and RGB channels.  I then took the H-Alpha amd mixed it with the red channel at 70% and the blue channel at 15% to create a new RGB image.  This is a large planetary nebula, the FOV accross is 3 degrees
