NGC 51 Galaxy Group

This is a wonderful rarely imaged galaxy group located 230 million light years away in the constellation of Andromeda at a declination of +48 degrees. This FOV is amazing because all of these galaxies have interesting structures, some of which are disturbed. The galaxies are around 100,000 light years in diameter. Most unusual is that, unlike most galaxy groupings, this is a true group - all are a similar distance away from us, although most seem to be far enough apart from each other not to be interacting.

The main galaxies here are in 2 rows of threes. Across the top are 3 NGC galaxies: NGC 51, 49, and 48. In case you were wondering why NGC 50 was left out, it is far across the sky in the southern hemisphere. This is a good illustration of how NGC galaxies are numbered in strict ascending RA corrdinate order, without regard to the declination. If you are viewing a group of objects in an evening, it is usually not efficient to view them in NGC order as you might first think. You may be bouncing around the sky.

NGC 51 is the most interesting, looking like 2 galaxies in the late stage of a merger. NGC 48 has a warped disk and a unusual straight bright arm segment. These galaxies range in magnitude from 14 to 15.

Across the bottom are 3 IC galaxies: IC 1536, 1535, and 1534. My favorite of these is the ring galaxy at lower right. These galaxies range in magnitude from 15 to 16.

If these were a bit closer to us, they would be one of the most interesting and most imaged objects in the sky.

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.
