M31 reprocessed using GAME

Revision title: Adjusted black point

Low hanging fruit!

This one joins the vast myriad of images of M31.

M31 (Andromeda galaxy) - Sept 4, 2021

One of our closest galactic neighbours. I took this one at the star party that happened at Spruce Woods park, Manitoba on the September long weekend.
Lots (!!) of dew to mess with the optics, but this evening provided was one of the best skies I have seen in my short life as an astrophotographer. Bortle 2 but with fantastic seeing - I had some of the highest star quality numbers seen while stacking in APP, a testament to how the gods quelled the disturbances that usually plague our latitude.

The entire evening was kicked off by a bino tour of the skies by our local guru Gerry ... who gave the group an amazingly detailed walk through Sagittarius (best visual of M8 I have ever seen - not to mention M7 - Ptolemy's cluster), other asterisms and constellations.

This image:

- 43 x 300 sec exposure
- 70 mm Stellarvue apo
- 2600 mc pro camera cooled to -10
- guided with EQ6 using ZWO developed software for ASIair pro and processed with APP and Pixinsight

For the first time, I did not use Photoshop to tweak and reduce the size of the file eg, no PNG conversion. Thus the size of the file is pretty large, my apologies.

Thanks for looking!

Clear skies, and your comments are most welcome.

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.
