Presented in 1920x1200 HD pixels, this image is centered on the Snake Nebula in the constellation Ophiuchus (very near Scorpius and The Pipe Nebula). There are a number of other dark nebulae in the picture. Below & left of the snake is a very dark spot which is B68, with B69, B70, and B74 swinging left and up. The bright star is 44 Oph and above that is part of the pipe nebula. To the right of the snake we have B261, which combined with B262 to the right makes a cool looking wing shape. Below, on the right edge is a large dark blotch, B67a.
This is 22*5 = 110 minutes total exposure from the Spring 2011 Davis Mountains trip. Takahashi FSQ-85 Telescope with reducer, AP 900GTO mount, QHY8 CCD Camera. The FSQ-85 is 323mm focal length, f 3.86 per Takahashi specs.


I was planning to shoot this in RGB, but the B didn't get done due to weather conditions. I copied the green channel to blue to get the RGB color image above. 7 G and 7 R binned 2x2. I don't recommend narrowband filters for dark nebula. I was running two cameras at the time and was primarily focused on the FSQ shot. I was looking forward to getting a "true" sense of the star colors in this area, though. I'll come back to it someday perhaps!
