M51 - The Grand Design Whirlpool Galaxy

When they say "Grand Design", they really meant it this time

The beautiful, face-on spiral interacting with, and mutually distorting, its galactic neighbor is a truly wondrous cosmic sight! And to think that if you lived in either of those galaxies, nothing much would change for you and you'd pass right through each other!!

Finally got around to properly processing this data I captured around Christmas last year.

I was also experimenting with different techniques to add Ha data in - NBRGBCombination, EmissionLineIntegration, etc. In the end, though, Bill Blanshan's advanced blending script in Galaxy mode along with synthesizing a new luminance layer by combining luminance exposures and luminance from HaRGB rendered the best results.

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.
