M31 revisit

I revisited M31 after two years, just to see, what I can get out of it in one night. I also used several new processing approaches I did not use before, like fully separate editing of stars and object after stretching (StarNet++ ist just awesome) and switching early to Photoshop.

Obviously there are some flaws and things to improve:

- Wrong spacing between reducer and sensor and also some tilt

- I should have imaged the stars separately with a shorter exposure time and at GAIN 0

- As soon as my imaging train is corrected, I will triple the integration time

Maybe the items, that are on back-order, will arrive early enough to make a second go this year

Title: v2

Description: As a beginner, I learn something new every time I photograph a new DSO or process an image with tools like PixInsight. Like many, I go back from time to time and see what I can get out of older data with my new knowledge. I think the first version lacks the impression of the brightness of the core (gone too far with bringing out dust in the core). It also has an unnatural look to the stars, because I reduced them way too much. And finally, the saturation of M31 was too high (especially the strong yellow tint).
I fixed all of this in my new revision and used some more recent tools to get a better result overall.

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.
