Arp 279 (NGC1253, NGC1253A)

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

This pair of galaxies are fairly large as a group. NGC1253 is the northern and larger one while NGC1253A is to the south and smaller. Both of them appear to be pretty distorted spirals with only remnants of arms visible. NGC1253 has a more distinct arm remnant on the north side, but the south side just shows two parallel streams of material. The western edge also shows some definition. A slightly brighter nucleus can be seen within a very extended halo. A faint star very near the nucleus and then a brighter one near the southern edge. A dark area separates the two galaxies where a single 12.2m star lives. NGC1253A is much smaller, elongated and also has a faint nucleus. It also appears to have an arm at right-angles to the main arm (main arm oriented about E/W but curves like a flat "S", where the little spur is to the north and straight). As the session progresses near 45 minutes, this spur takes on the appearance of a fish hook (in my capture its shaped sort of like an "L" or an upside down question mark but is a brighter section of the halo/arms. Appears to be a small group of 4 faint galaxies off to the west of NGC1253 that form a little diamond or parallelogram. Very interesting galaxy group. SC only annotates PGC 1082999 @ 17.9m.

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.
