Horsehead & Flame Nebulae & surrounding dust

-----------------------------------

This image is from 3 hours of colour and 7 hours of Hydrogen-alpha data I collected last month, on the region around the Horsehead and Flame nebulae.

Not totally happy with the result, but I am still learning how to process the minor details. Had a tough time trying to remove the huge disruptive glare from Alnilam on the left side of the image.

Details on the objects:

Visible in the center of the image is the dark silhouette of the "Horsehead" nebula: a dark cloud of gas and dust in front of a large emission nebula (red/pink colour) caused by ionized hydrogen gas.

The "Flame" nebula, located in the lower-left, is a bright region of active star formation surrounded by dust.

On the center-left: the bright star 'Alnitak', the eastern-most star of "Orion's belt", which is easily visible with the naked eye even from heavy light pollution.

Also visible around the Horsehead and Flame nebulae is faint dust which is part of a much bigger molecular cloud in Orion (the same dust complex found around M42).

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.
