Stephan's Quintet in Pegasus

Stephan’s Quintet is a group of 5 gravitationally interacting galaxies lying 290 million light-years from Earth in the constellation Pegasus. It was discovered by French astronomer Edouard Stephan. The galaxies in the cluster are, proceeding clockwise from the galaxy in the upper left corner, NGC 7319 with tidal tails trailing off below, interacting spiral galaxies NGC 7318B (left) and NGC 7318 A, NGC 7317, and NGC 7320. The face-on spiral galaxy to the upper left of the cluster is NGC 7320C. The edge-on spiral galaxy at the far left center of the image is PGC69346. This is a full frame shot of the group, which is actually quite small in apparent size in the sky. For more detail and comparison to the famous image published from the James Webb Space Telescope, see the zoomed in view on this website.

Exposures: L:R:G:B = 380:120:120:120 minutes =2 hours 12 hours, 20 minutes total exposure, completely unguided.
