Orion's Belt, M42, Running Man, Flame and Horsehead Nebulae Mosaic in Ha

Revision title: Flame, Horsehead, Orion Nebula Mosaic

The snow is deep, it's cold, light pollution is awful and amplified because of the snow, and the time available to shoot because of the horrendous weather is short...so narrowband it is. This is a mosaic of 3 panels shot in the second half of January, 2022 when temperatures were -15 to -20 C and about 40 cm of snow lay on the ground. The 3 nm Ha filter seems to be doing what it's meant to. Each panel is about 100 two minute subs, the most I could get under the circumstances (for now).

Title: Flame, Horsehead, Orion Nebula Mosaic

Description: This is my first mosaic effort, imaged over several weeks just to get abbot 3 hrs per panel. It has been a horrible winter coupled with clear skies corresponding to bright moon phases. So a narrowband project seemed worthwhile.

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.
