M31 - The Andreomeda Galaxy

I've been experimenting with combining RGB data with narrow-band data (primarily HaOiii using an Optolong L-enhance finter). Here is 5hs, 21min of data consisting of:

01/15/2024 - 60 x 60s + 21 x 120s with Optolong L-Pro filter
01/16/2024 - 62 x 60s + 31 x 120s with Optolong L-Enhance filter
01/17/2024 - 31 x 120s + 11 x 180s with Optolong L-Pro filter

The L-enhance really brings out the Ha (red) in the arms of the galaxy.

I processed this by combining all of the masters from each WBPP session using ImageIntegration (I also tried various other approaches, including combining the RGB masters using HDR combination, then combining in the narrowband data using NBRGBCombination, but I think this image came out the best).

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.
