NGC 317

This rarely imaged object is a tiny pair of interacting galaxies located 220 million light years away in the constellation of Andromeda at a declination of +44 degrees.

The central spiral galaxy is PGC 3345. This almost edge-on galaxy spans 2.5 arc-minutes in our apparent view, which corresponds to a diameter of 150,000 light years. Although it is hard to see the galaxy structure from our perspective, I like the dust clouds which surround the bright core and the one heavy arm which extends to the right.

The companion galaxy just to the left is a lenticular galaxy, PGC 3442. This galaxy looks to be about the same size as PGC 3345.

The galaxy in the upper right corner is MCG+07-03-011. It doesn't look to me that this galaxy is interacting with the other two.

This is the first color image of this object on Astrobin. You will see that I took this image several months ago - I made numerous processing attempts of this challenging object.

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.
