Coddington's Nebula or IC 2574

Often ignored because of the nearby M81 and M82, Coddington's Nebula lies north of the bowl of the Big Dipper. IC 2574 is part of the M81 group of galaxies and is classified as a dwarf spiral at a distance of 13 million light years.

There are some intense star forming regions that were easy to blow out in processing. My Ha signal was a bit of a disappointment given the nebulosity in other images around the web. I thought there was an interesting loop of stars nearby and used that to determine my cropping.

It was discovered by Edwin Coddington in 1898. Honestly, I thought there was going to be some profound link to the astronomer or interesting story given its name, but I cannot see any reason why it has the special moniker.

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.
