Revision title: More broadband time added and continuum subtraction on Ha regions

Starting my third year of astrophotography and decided to go back to one of the first galaxies I imaged. I had about 4 solid days of clear skies right after the moon went to 50%, and with nothing else really catching my interest I decided to throw my 10" newtonian at these two. First night I decided to go RGB with the L-pro and hope the moon didn't mess with the gradient that much. Did have some thin cirrus roll through that made me lose about an hour. The next three nights I swapped to the L-Ultimate to see what I could get with the Ha. I decided to use this time to give continuum subtraction a try and hope I did just fine. Its great going back to my old image and seeing how far Ive gotten with astrophotography in just over 2 years.

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.
