M101 Pinwheel Galaxy

This is the first of what I hope to be a series of photos from a 600 frame set I took over 5 nights. The first shot will be LRGB with Ha to be added later. I'm using this data to learn how to better process.

Starfield is Luminous only merge with LRGB galaxy.

I probably processed this set 4-5 times before settling on a first image to post. Lot more testing and process rounds to go to get something better and more in line with my intended results. H-Alpha should make a good one when I get to it. I also have some new noise reduction trys to come earlier in the processing which will hopefully yield some cleaner future images.

Description: New workflow to get more natural color. LRGB - H-Alpha will be in next version.

Description: This version has H-Alpha data integrated. Retouched the background to reduce blue saturation that was flooding the right side of the image. Stars have been reduced and softened to compete less with M101. Many types of masks and Pixel Math routines utilized.

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.
