M 31 - LhaRGB - ASI 2600 MM Pro "first light"

Revision title: Reprocessed with new approach for mixing Ha into RGB

This is the first light of the ASI 2600 MM Pro I received recently.

Natural fit for the Takahashi 85 EDX4 from the sampling perspective and given the local suburban sky quality here.

Had a decent night, with relatively low number of subs.

Each sub captured is worth almost 50 Mb in size... storage capacity and processing power is going to be the next challenge!

Version A: The pre-processing was performed in AstroPixel Processor, mixing and denoising in Startools, final color adjustment in Photoshop. Dark and soft processing.

Version B: post-processing reworked in PixInsight . My mates didn't like the colors, had to do something.

The core of M31 could probably be better detailed, there's so much dynamic range in the image; I'm just too scared to ruin the image altogether...!

Hope you like it as it is.

Comments/feedback welcome.

Details in M101 are just incredible. Also amazing are those tiny galaxies visible in the sky background.

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.
