OriginStack sample session: Stephan's Quintet, galaxy group - 45 raw Celestron Origin frames

45 raw Celestron Origin light frames of Stephan's Quintet (galaxy group), 10 s each, captured 2025-10-11, with the session's own dark, flat and bias frames and the capture app's info.json. A compact group of galaxies in a rich star field. Colour sensor (Origin178), 6-inch f/2.2 RASA, 3056×2048 Bayer FITS. Filter setting in the headers: Clear. The frames are the best of the session by quality score, one from each of 45 consecutive time bins. The observer's location, GPS, airmass, session id and camera serial number were removed from the headers and json files; pixel data is unchanged. Capture time and the target's coordinates were kept. Stack it with OriginStack: python originstack.py -d "03_galaxy_group_Stephans_Quintet" -o stack.fits. With OriginStack 2.21: 45 of 45 frames accepted; median star width in the frames about 3.9 px. The file ending _expected_result.jpg is the preview that run produced. Zip: 489 MB, SHA-256 9b23bbf118459a9aaa96bfdc15237d328de9959f89be5420b7f36e6c20006559.
