Horsehead and Flame Nebula, HaLRGB

The iconic Horsehead, known as Barnard 33, is located just south of Altinak (Zeta Orionis), the easternmost star in Orion's belt. B33 is silhouetted against the bright Ha-rich nebula, IC 434. Nearby NGC 2024, the Flame Nebula (also known as Sh2-277), is an emission nebula whose source is an O-type star IRS 2b that is obscured by the dense dust in the core of the nebula; this dust also obscures an open cluster that is best visualized in xray and infrared wavelengths but remain nearly completely obscured in the visible spectrum.

The plan for this winter was to capture 2-3x the amount of data that this image contains, but the best made plans were no match for the relentless cloud cover that characterized the winter of 2024.

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.
