M31 bathing in ionised Hydrogen

M31 the Andromeda Galaxy bathed in nebulosity is thought to be part of a broader band width of emission. Imaged with the FSQ 106ed at f3.6 and the stunning ZWOASI6200 full frame Cmos camera. Exposure times were 140 x 240s frames in H-a with LRGB 100 x 180s in each channel a total of nearly 31hours. The faint H-alpha in the background was very difficult for me to pull out probably making this my most challenging process to date.

Thanks for looking

Description: With this version I have done some work on the background Luminance layer. It has additional structure in the Luminance that I thought would be worth showing.

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.
