Dear Astro Fellows,

I don't think it is necessary to present this really famous nebula. What a tough object to process! This is my first time processing bicolor Ha/OIII images and I must admit that it took me quite some time. I found it very difficult to reveal the thin OIII veil. First time I'm adding RGB stars too. I have used Ha layer as Red and the OIII layer as Green and Blue, a very basic RGB combination. Colors were then modified using curves. Please don't hesitate to comment and tell me what could be improved. I bet this image is far from beeing optimal as I integrated for quite some time. Thanks for watching and clear skies ! Brice

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.
