This is a challenging area to image because the reflection nebulae here are very faint and you have the potential for glare from Mintaka and Alnilam. I’ve tried to capture it from my backyard with limited success, but having the incredibly clear and dark skies of Chile available remotely allowed me to capture it much more clearly. (It doesn’t hurt that Orion climbs to 60 degrees altitude in Chile, either.) I didn’t use an H-alpha filter, but the whole of Orion is filled with both ionized and molecular gas, so it still comes through well in this LRGB image.Mintaka is at upper-right. At left, from top to bottom, the reflection nebulae are IC423 (known as the Teardrop Nebula), IC424, and IC426. All were discovered by Williamina Flemming in 1888. The larger nebula at center-right is LBN940, also known as the Epsilon Orionis Nebula. This might be the “lost” NGC object NGC1990, and sometimes that designation is used, though William Herschel seems to have indicated that his object was closer to Alnilam. In that case, it was probably glare or reflections in his 18″ scope.The arc of nebulosity around Mintaka doesn’t seem to have its own designation, as it isn’t really a discrete object; it continues southward for several degrees, merging into the greater Orion molecular cloud. Most software will mark the center of LBN918 here, but that is Lynd’s entry for the whole of the Orion cloud, spanning 6×10 degrees.

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.
