M106 LRGB with HaOIII core

I was attracted to M106 by its nice apparent size and the anomalous arms. I've already presented the Ha and OIII data I shot on the core/arms - see my earlier post. Here I've finally gotten enough decent LRGB to present the full image.

The narrowband data was combined with the broadband in Photoshop. I used the narrowband data as a layer blended as an overlay. This seemed to best pull out the structures while preserving as much of luminance profile as possible. I prefer to keep the galaxy cores brighter than the arms but still find some way to show the detail. That's always a challenge.

My yield was very low due to the poor skies YTD in the west. 30 hours of LRGB data made it from the Observatory to my processing computer and only 17.5 hours of that was used. Mostly due to transparency issues. I was able to use 25 of 28 hours of Ha/OIII data. So total time here is 42.5 hours, though that's pretty meaningless as the vast majority of pixels are from the 17 hours of LRGB.

Calibration, stacking and LRGB combination done in CCDStack.

DBE and SCNR done in PI.

Background and color noise reduction with Topaz DeNoise 5.1

Everything else was done in PS CC 2019.

I've heard a number of complaints about over saturation lately. Is this too much?

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.
