M33 (Pinwheel or Triangulum) in RGB with Ha

I had some M33 data with my C11 (and reducer) and also with the SVX152T, and got more (especially Ha) this year in small intervals. When I looked at the data I ended up discarding the C11 data, but the additional Ha brought out a lot more details than my prior attempt.

This is about 13.5 hour each of R, G, and B, plus 18.3 hours of Ha. I took a fairly heavy hand processing with HDRMT and LHE in Pixinsight to get some contrast in the Ha and dust lanes, and toned down the red a bit afterwards as it was too bright.

It was formed with a synthetic luminance which was mostly the mean of the other colors, with a MIN limit on Ha to specifically tone down that knot at about 3 o'clock, which otherwise saturated.

I welcome criticism or suggestions.

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.
