NGC 2174 - The Monkey Head

The NGC 2174, commonly known as the Monkey Head Nebula, is a diffuse emission nebula located in the constellation Orion. It is situated within the Orion Molecular Cloud Complex and is approximately 6,400 light-years away from Earth. NGC 2174 was not specifically cataloged by William Herschel, the famous German-born British astronomer, but was amongst his observations. The New General Catalogue (NGC), compiled by J.L.E. Dreyer, was published in 1888 and included many nebulae and other deep-sky objects. NGC 2174 was likely identified and cataloged during this period.

During the imaging of this target, the OIII signal was found to be very strong and the data acquired was the first where my new Antlia 2.5nm filter was used. This filter appears to yield better contrast with the background sky than wider bandpass filteres used in the past.

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.
