NGC 7293 Helix Nebula HOO+RGB stars

Revision title: Background slightly more black

The Helix Nebula is certainly, at least to me, one of the most beautiful object in the sky. It is also a difficult object to image, as it remains very low at my location. It is indeed never higher than 23° altitude. It is also at a time where night are not that long yet. Given these difficulty, I am very very happy with that result. The Ha signal picked up by OSC cameras is indeed incredible.

The processing was fairly classic. SIRIL for stacking dual narrowband and RGB data separately, then Pixinsight for all subsequent steps.

I hope that you enjoy it !

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.
