M 51 Whirlpool Galaxy HaLRGB Rural Kansas Skies

My first attempt to combined Ha, L, RGB all with the ASI 1600. Also, working on a new strategy with a mask stretch in pixinsight. Stars needs some work, but I am pleased with progression in the editing.

The whirlpool galaxy is a prototypical spiral galaxy. It is thought to have interacted with the smaller NGC 5195 galaxay as a close local neighbor.

The galaxy is estimated to be 23 million lights years away from earth. About the 160 billion solar masses or 43% the size as the Milky Way and Andromeda. The the galaxy measures an estimated 38,000 lights years across at it's central disc and 76,000 light years across overall measuring 11.2 × 6.9 arc seconds

Description: Fixed some of the star color with deconvolution and worked on color saturation. Also, first steps in to pixel math blending HDR with the original image for better sharpness/contrast. Hope to add better luminance data in the future that is bin 1x1 like the rest of the frames.

E

Description: Finshied 1x1 luminance data to update the RGB and Ha 1x1 lumiannce data. Also working with deconvulsion to clean up the stars. Progress, but still a work in progress.

Description: More zoom and slightly different color saturation

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.
