This is my lastest revision on M31. It now has 10.4 h of light subs, taken over multiple nights. Longuest integration time that I got on any target so far! Comments and feedback are always appreciated. I my previous post on my progress so far, I had written that I had 9h20, this was a mistake, it was actually 5h.

I combined 3 stacks in photoshop that I first calibrated in Astro Pixel Processor:

- 1 stack of 180s subs @ gain 200

- 1 stack of 180s subs @ gain 120

- 1 stack of 60s subs for the core

I find it a bit challenging using astro pixel processor to get the right signal to noise ratio, I might have stretched the data a bit too much before combining in photoshop. I now have on my todo list to process this data using photoshop only to compare the results, but that will be for another time.

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.
