Image Details | Right is 94.3 degrees E of N. Total integration time was 24m30s. Exposures 30s@305g, darks subtracted, UV/IR Cut Filter, dithered and recentered in SharpCap. Darks subtracted, no flats. Dithered and recentered in SharpCap. No guiding. Featured image and comparison rotated 90° and enhanced in Affinity Photo from original SharpCap capture.. |
Description | Despite an 88% moon, I was determined to capture a number of Arp galaxies in Andromeda, recognizing the window of opportunity this year was short. This was the second observation of the evening, and the target was fairly low in the west. I captured as much data as I could until I judged the thicker atmosphere and glow at the horizon would render further integration useless. SharpCap had some issue subtracting darks, so the full image exhibits what I take to be amp glow from the 294mc-pro camera. Nevertheless, while it won't win "Astrophoto of the Month", it does show Arp 145 clearly, with it's two bright centers and partially merged eliptical galaxies. |
