Arp 188: Tadpole Galaxy in Draco

(Click on the original revision for the full, wide-field version).

Arp 188, also known as UGC 10214 or PGC 57129, is a distorted galaxy in the constellation Draco at a distance of about 400 million light years. Including its long tail, the entire galaxy is under 4 arcminutes long, and its overall magnitude is just 14.7. The galaxy collided with another galaxy that is now behind it. For a better view, check out the awesome Hubble Telescope image of this galaxy, which shows the intruding galaxy departing behind it.

Part of the data for this image was obtained on two nights at Muleshoe National Wildlife Refuge in Texas; a third night of data was acquired at Capitan Gap, Lincoln Co., NM, the darkest site at which I have ever imaged. Without extremely dark skies, this galaxy would have been all but impossible to image in color. It was the most difficult object I have ever had to process,and I would advocate using a more sensitive/lower noise camera if you plan to tackle it. RGB frames were just barely above darks, and it took every ounce of noise reduction I could muster to pull the colors out. It has taken a few revisions to get the colors and sky background to my liking.

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.
