Horsehead and Flame Nebula

The Horsehead Nebula (Barnard 33), approximately 1500 light years away close to the most eastern star in Orion's Belt, is a hydrogen gas cloud made visible by the background nebulosity.

The Flame Nebula (NGC 2024) is also located in the Orion constellation about 1400 light years away and it is illuminated by Alnitak, a hot blue supergiant (and a pain for the astrophotographers due to its immense brightness). The Flame Nebula is the home of a cluster of several hundred very young stars.

Shot in RGB and Ha, combined in astropixel processor (HaRGB) and then used Ha as a Luminance Layer. The nebulosity was processed in Adobe Photoshop after the stars were removed through Starnet++ and then combined it to the HaRGB containing the stars.

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.
