Stephan's Quintet

Stephan's Quintet - Interacting galaxy group

4 of 5 galaxies captured in this shot. These are the "talking galaxy angels" featured in the movie "It's a Wonderful Life".

Magnitude: 13.6-14.8
Location: Pegasus
Date: Oct 7/04
Exposures: 16
Exposure length: 30 seconds
Amp on setting: OFF
Brightness: 100
Gain: 40
Processing: Acquired, aligned, stacked, histogram adjusted in K3CCDtools, noise reduction in NeatImage

Notes: This is a deep shot (345M light years). The dark frame subtraction was an issue. I want to try this again with a skyglow filter, longer exposure and more frames to see if more detail can be captured.
