IC 2118 (Witch Head Nebula), NGC 1788 and the Dark Nebulae surrounding it.

Cataloged as IC 2118, The Witch Head Nebula is a faint reflection nebula in the constellation Orion and is believed to be an ancient supernova remnant.
Its appearance resembles the side profile of a Witch face. The dusty areas of this nebula are lit by the nearby star Rigel.
It lies at a distance of 1,000 light years from Earth and has an apparent magnitude of 13.
NGC 1788 is an unusual reflection nebula surrounded by a glowing red ring of hydrogen gas.
The stars inside the nebula are only about a million years old, which is very young compared to most stars.
The ring of glowing hydrogen gas is energized by nearby hot, massive stars.
LDN 1616 is a very opaque dark nebula that is apparently a part of NGC 1788. Distance: 1,300 Ly.

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.
