The Horsehead in SHH

This is a narrow band image where I have added false colour to the sulphur and hydrogen emissions. I saw this colour palette on Astrobin fell in love with it, and tried to re-create it as best I could.
Sulphur data is red and Hydrogen was allocated to green and blue to make a colour image.
The Horsehead nebula is a dark nebula located in the constellation of Orion near Orion‘s belt. It is a very dramatic part of space, and an object that is not really visible visually but very obvious photographically. And who knew that the nearby reflection nebula full of sulfur, and therefore red in my image!!

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.
