Horsehead (IC 434) and Flame (NGC 2024) Sh2-277) Nebulae

The Horsehead Nebula glows very bright red in H-alpha and has a very prominent (and iconic) horse head shaped dark nebula (Barnard 33) carved out on one side. The Flame Nebulae, a bright emission nebula, also has a dark nebula at its center. Both nebulae are contained in the star-forming region of the Orion Molecular Cloud Complex and are illuminated by Alnitak, a triple star at the eastern end of Orion's Belt.The moon was smiling down at about 98% illumination for most of the 4-hour imaging session, so the dual narrowband filter did double duty for this imaging session. Askar 107PHQ Petzval Quadruplet (749mm fL)

ZWO AM5 mount with guiding via ASIAir Plus using an ASI178mm mini and a 60mm F4 guide scope

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.
