M45 (Pleiades) in HOORGB

I've wanted to take this picture for a couple of years, but whenever I could get to my dark sky site, it was cloudy. The stars finally aligned (literally) and I was able to get a good amount of RGB data from my dark sky site this winter.

During my research for taking this photo, I noticed that some images had small amount of faint Hydrogen Alpha immediately around M45, so I figured I'd pile on some HA data for my wide field image and see if any more hydrogen would present itself...I was pleasantly surprised to find some wispy streams of hydrogen that I'd never seen before, right outside of the star cluster.

The RGB data was taken from my dark sky site in Bone Cave, TN. The narrowband data was taken from my backyard in Nashville, TN.

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.
