M31 Andromeda Galaxy with gas and dust in HOLRGB

When I saw the amazing deep image of M31 by Marcel, Xavier, and Yann last year (https://www.astrobin.com/1d8ivk/), I really wanted to try my hand at a deep exposure myself. I also wanted to go pretty deep on the LRGB to pull out the broadband detail. I really liked the LRGB data, and while the Ha and Oiii data showed the same areas, my narrowband data did not seem as deep and clean as theirs even though there was a lot of integration time. I think that I might be starting to see a fall off in my NB filters due to shooting at f3.6 with standard 3nm narrowband filters. Lowering the signal intensity. Something that I plan to test at some point.

I do really like the "star stream" on the right side of Andromeda. There is also some interesting structured dust in the foreground from our home galaxy.

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.
