NGC 3769 - Arp 280 in Ursa Major.

Here's another Arp galaxy, this one is Arp 280, ngc 3769, an interacting pair of galaxies in Ursa Major. It is about 50 MLy away from us and is a member of the Ursa Major cloud of galaxies which also includes M108 and M109.

NGC 3769 is mag. 11.7, ngc 3769a, the smaller of the 2 is mag. 14.7. On the Northern edge of NGC 3769 is a small smudge described as a 'knot' in the Arp atlas. SKY-MAP.ORG shows it to be 2 seperate entities with 2 seperate numbers and a mags of 17 and 18 respectively. It looks like an edge-on spiral, probably seen through ngc 3769 but it could be interacting with 3769. Difficult to say as I can't find any redshift data for the 'knot'.

You can just see it in my image, which consists of a total of 96 minutes of exposure made up from 2, 3 and 4 minutes subs.

Only another 150 or so Arps to go!

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.
