Horsehead & Flame Nebulae

The Horsehead and Flame Nebulae are nebulae located on Orion’s belt. The bright blue star in the image between the two nebulae is actually the easternmost star of Orion’s Belt, Alnitak. Alnitak is a blue supergiant star 33 times the mass of our Sun and is actually part of a triple star system. The Horsehead Nebula is a dark cloud of dust and gas blocking the light being given off by the ionized hydrogen gas in the nebula behind the horsehead. The Flame nebula is an emission nebula that is home to hundreds of young stars which have formed out of the nebula’s gas cloud, some of these stars are as young as 200,000 years old.

I took this one in broadband RGB as it was during just a ~20% illuminated Moon and then I added in some Ha to pull out the details on the object. I found maintaining the correct color balance was challenging when adding the Ha to the RGB and probably would have been well served to add in OIII data but that filter wasn’t in my filter wheel on this particular night. It was COLD the night I captured this object, like -22 deg C (-8 F) cold.

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.
