M51 in LRGB, with Hα Added

I am enjoying going back to some of my previously imaged galaxies and getting a much closer and more detailed view using this longer focal length telescope. A previous widefield image captured at 580mm for only 48 minutes was my only image of this object taken prior to this posting (visible on this Astrobin account).

This iconic target is one of the most mesmerizing objects in the night sky. First discovered by Charles Messier in 1773, M51 contains 2 interacting galaxies, the larger NGC 5194 face on spiral, and the smaller NGC 5195 galaxy (the yellow object to the right of the spiral in this image). These objects are bright enough to be detected with binoculars under dark skies, and reside approximately 31 million light years distant in the Canes Venatici constellation.

This was imaged in LRGB filters with additional Hα data added in to accentuate the reddish pink star forming regions. As always, comments and critiques are welcome, and thanks for looking!

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.
