(Updated Dec. 2017)

This is a large region of nebulosity (mostly hydrogen) around the star Sadr in the constellation Cygnus. From Wa-chur-ed Observatory in June of 2016. As is usual for this observatory, this is a narrowband image, processed to yield a false-color image in which the yellow represents S-2 and the blue represents O-3.  Both colors are then modulated by the brightness of the H-a channel.

The bright star near the center is Sadr, which is the central star in the constellation Cygnus.

Scope: AT111EDT at f/5.7
Mount: AP Mach1
Camera: QSI 683 at –20C
Exposure: 13 x 900 seconds H-a, 10 x 900 seconds O-3, 8 x 900 seconds S-2 (7 hrs 45 mins total)


About Greg Marshall

I am a retired electronics engineer and after a few months of enjoying my leisure I began to miss doing product development. My astronomy hobby always needed new solutions to unique problems, so I decided that whenever I came up with a good solution I would try to make it available to others.
