The Crescent in HaGO

The Crescent Nebula. A quite common target in the northern hemisphere- understandably, as the intriguing Ha structure is embedded in a shell of Oxygen, giving this targets a very unique look.

I decided to make this my second Image in the HaGO pallet, as it combines the defined structures of Narrowband imaging with a more natural look than classic Hubble pallet. Hence my focus during processing was to keep things natural and nevertheless bring out the details in the nebula as well as the faint Ha formations in the background. Combination of Ha and O3 were used as artifical luminance.

Check out Dylan O’Donnell’s youtube video on HaGO to learn more about the HaGO approach.

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.
