The Eagle Nebula in Serpens
with 10" f/3.9 Astrograph
Uploaded 7/10/16

This is what you call a VERY tight composition! South up, I had to really spend some time getting such a huge nebula to fit well in the field of the 10 inch. The "Hubble's Pillars" are in the center of this nebula, and there is more red emission nebulosity in this image than sky. This is an RGB image, with the R channel having twice as many sub frames averaged together as the G and B channels. This reduces the noise in the dominant color in this image and allows for more comprehensive processing.
