This image shows the Boogeyman Nebula on the lower right and the Casper Nebula on the upper left in one field of view center of Bernard Loop in the Orion.

The Boogeyman Nebula is a monster similar to a ghost or goblin of legend in the West. Its official name is LDN1622 and it consists of a dark nebula and some Ha (ionized hydrogen regions).

Casper Nebula is a little ghost that appeared in a cartoon movie titled The Friendly Ghost in the mid-20th century. It is called the Casper Nebula because it resembles Casper the Little Ghost. Officially named M78, this reflection nebula is attractive due to the contrast between the blue region and the surrounding red Ha region.

The difference in brightness from Bernard Loop is so great, and since LDN1622, M78, and Bernard Loop are all objects with different characteristics, it is necessary to process after applying a mask to the three objects separately when correcting, so it is bright but difficult to process.

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.
