M66 had generational process quite similar to that of M65 in that it started life in 2005 as a short exposure/unguided project to later evolve into a long exposure/guided one. One difference here is that the galaxy is intrinsically brighter that its closest member of the Leo Triplet and therefore it is easier to capture enough colour data (and possibly because is more colour-rich too) to bring those colours out. I also had the good sense to capture enough H-alpha data to bring out the HII regions in the galaxy's arms. Finally, and more important lesson, the colour and luminance total integrations are better balanced than M65 and therefore it easier to produce a better L-RGB image.

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.
