Stephan's Quintet and the Wreckage of a Galactic Collision

The five galaxies of Stephan's Quintet include two galaxies that have collided (NGC 7318A and NGC 7318B,) another galaxy in the neighborhood along with NGC 7320 that sits in the foreground. The blue color of the NBC 7320 is a strong clue that it lies closer than the redder and more distant interacting galaxies. NGC 7320C (the small barred spiral to the right of the main group) is not a part of the Quintet but it has a tidal tail that ties it to NGC 7319 so there are probably five galaxies tied together in the same distant region of space. Photons from these galaxies have traveled for 210 - 340 million years before reaching Earth.

At only 3.5 arc-minutes, the angular size of this cluster is fairly small and each galaxy is a bit fainter than 14th magnitude so it is not an easy object to image. This data was obtained with my newly repaired FL-ML16803 camera over a few nights with moderately good seeing. Processing was quite difficult because of the small size of the image on the sensor. Keep in mind that this image only shows a region covering a little less than 3/8 of the dimensions of the KAI-16803 sensor. This data was 2x drizzled and cropped to produce this result. A couple of years ago, this object was an inspiration to abandon my DSLR camera and move to a mono-CCD camera. I'd really like to get more detail on this object so it may become a new inspiration to move to a bigger scope. Under the right conditions I suspect that a 20" or 24" should show noticeably more detail.

As always C&C are welcome.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
