I'm very glad to release my first SHO project. I really enjoyed learning and processing narrowband. Please tell me what you think could be improved or reworked as I am seeking for progress ! I know my focusing could be better and will work on this as well as the mount guiding the next months. Thanks for watching and Clears skies ! Brice

Description: Thanks to my friends Christophe Perroud and Michael Feingenbaum advice, comments and honesty I decided to rework this picture since I believe really passed the line on the original one. I thus decided to lower the green to 25% and dramaticaly reduce HUE and sat on this version too. Thanks you very much guys for opening my eyes.

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.
