Conditions: 50 degrees; calm, very good seeing
Exposures: Ha: 6 hrs 15 min (15 min subs); RGB: 40 min each (10 min subs) for a total of 8 hrs 15 minutes
First attempt at collecting color data (RGB) from backyard site. Because of their wide spectral range and overlap, color information is usually washed out by urban glow. However this image was taken during a new moon under very dark and transparent skies. Color data were uncontaminated.
FOV = 126 x 85 arc minutes
