NGC 752 Open Cluster

NGC 752 Open Cluster is in the constellation Andromeda. The cluster is just visible to the naked eye in very dark conditions. Since the Moon was waxing gibbous at 78% on November 22, I used a hydrogen oriented filter to filter out the moonlight. The filter also makes the stars look smaller.

North (toward Polaris) is up in the photo. The picture was taken with a fully modified Canon Rebel camera (this is my one shot color camera) on a TEC 140 telescope in the Alpenglow-Torrey House Observatory in the dark sky community of Torrey, Utah (Bortle 2-3).

The 12 best of 14 120-second sub-frames were used and stacked in Deep Sky Stacker = 24 minute photo. Unguided, binned 2X2 in the SkyX (to make smaller files for internet transfer), no calibration frames. Processed in Photoshop (CS5).
