Rosette Nebula HOO image extracted from L-enhance dual band filter (Rosette Nebula in HOO. Revision of my initial attempt.)

HOO image of Rosette Nebula. February 10, 2022. H-alpha and O-III data extracted from L-Enhance filter image session by Sirl. Canon 400mm F2.8 lens on Canon full spectrum 60D. 169 x 30 sec. Sky Watcher EQ6-R Pro mount. Tracking only, no guiding used. 9 day old moon nearby. This was my first attempt at making a HOO false color image. Examples of other folks work with this technique seemed to show considerable variation. I'm not sure how representative this image is of the technique, especially since I used a dual band filter with extraction of the bands in Sirl.

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.
