M31 The Andromeda Galaxy in HaLRGB

My second ever M31 capture, this time with a cooled CMOS mono camera and filters versus my previous DSLR effort about a year ago.

It's an early M31, I was too impatient to wait for the autumn/fall evenings when this incredible, awe-inspiring object will be highest in the sky and went for it in late summer here in the Northern Hemisphere.

You all know the score with M31...2.5 million light years away and heading towards us...the furthest object from earth that can be seen by the naked eye (not in my back garden though)...a trillion or so stars making it at least twice as large as our Milky Way...was initially thought to be a nebula, until Hubble figured out that it was way too far away from us for that and had to be another galaxy...there's so much to say about Andromeda.

Captured using APT, pre-processed using APP and post-processed in Pixinsight. Edit: An extra night of data added using NINA.

Thanks for looking, and clear skies!

Description: Had another go at this, including some new data captured with N.I.N.A....cut down on sharpening and saturation and also culled some of the original data due to high FHWMs.

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.
