Horsehead and Flame Nebula Ha + OSC

The famous Horsehead Nebula is a dark emission nebula with thick cosmic dust obscuring a young stellar nursing. The Horsehead is measured to be approximately 3 light years in size.

The Flame nebula is immediately next to Alnitak, which is the farthest east star visible in Orion's belt. You can see Alnitak;s large diffraction spikes. The nebula is caused by Alnitak shinning light specifically in Ultraviolet wavelengths on hydrogen dust clouds that then release the hydrogen alpha specific wavelength. The dark area of the flame nebula has a hidden cluster of young stars be born when imaged in xray and infrared. The Nebula is an average estimate of 1,200 light years away.

The image ins a combination of OSC using my ASI 294 MC pro and my ASI 1600 MM pro for the hydrogen alpha layer.

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.
