M27 Dumbbell nebula in dynamic bicolor mapping w/ RGB stars

This is a very known DSO, a must-have for any astrophotographer, that looks beautiful in standard HOO or H_HO_O palettes. This one is an alternative color mapping schema, based on dynamic, non-linear parameters to transform HSO into RGB, as follows:R = iif(H>.15, H, H*.8+O*.2)
G = iif(H>.5, 1-(1-O)*(1-(H-.5)),O*(H+.5))
B = iif(O>.1,O,(H*.3)+(O*.2))

Total integration time: 13h 16m

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.
