NGC 2239 -- Rosette Nebula in Narrowband HOS

Revision title: Slightly revised color

The Rosette Nebula, NGC 2239, captured in narrowband where RGB=HOS during the period January 2-4, 2022. Sub-exposures were unguided and six-minute duration. Four hours were collected of each channel for a total 12-hour integration. The color pallete was chosen to emphasize the red of Ha, with R:G:B = 60H+40O, 30H+30O+40S, 50O+50H.

Title: Reprocess with a revised channel/color emphasis

Description: Revised processing of original data with more emphasis on sulfur channel (B), less emphasis oxygen (G). HOS = RGB = 60Ha+40O, 30Ha+30O+40S, 50O+50S. Also left the data at the original bin2, as was collected, and no binning was performed during processing.

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.
