Sadr to 32 Cyg, 2 Panel Mosaic, Ha

Gamma Cygni Mosiac

July 8th, 2017

I plan for this to be a four panel mosaic, and eventually become HaRGB. For now, however, I am posting 2 of the 3 frames I have captured.

Object Details: Gamma Cygni, aka Sadr, is the bright star on the left side of the image, easily visible with the naked eye. It is surrounded by what is called the “Gamma Cygni nebula” or the Butterfly nebula, which is a hydrogen rich star forming region. Slightly to the left of center is the reflection nebulae complex NGC 6914, not visible in hydrogen light but identifiable because of it’s dark nebulae. Below center is the faint and difficult to capture propeller nebula, loosely cataloged DWB 111. The right hand of the image is comprised of filaments of HII emission. 32 Cygni is the bright star on the very border of the image (right).
