M106 Ha-L_RGB

Seems simple enough: 2.5 hours Ha, 2.5 hours of luminance, an hour each of blue and green...but only 45 minutes of red...mostly because this should-have-been-straightforward project took nearly two months to complete caputure. Cloud, cloud and more cloud--not going to complain, it is winter after all.

I tried numerous methods of adding the Ha, trying to get a result that wasn't overbearing and I think I have a reasonable result. I settled on the result from a continuum subtraction method for the Ha-RGB combination, using a starless version of the continuumHa result. This seemed to save the background and didn't affect the stars, of course. My attempt at adding luminance sort of overpowered the colour of the galaxies, so I backed off a bit on the stretch of L and got something I could work with a bit better for colour. Overall still pretty noisy, but between BXT and NXT, it isn't too bad. Way better than my first attempt at M106 about 4 years gone now.

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.
