The Monkey Head Nebula is a star-forming region located between the constellations Gemini and Orion. Newborn stars in the center of the nebula illuminate the surrounding gases with energetic radiation and strong stellar winds that erode the lower-density materials. Higher density materials resist the erosion forming pillars and peaks along the inner edge, especially noticeable in the upper portion of the nebula as oriented in this image.

I was able to collect about 18 hours of data during two successive clear nights at the end of November. I had planned on acquiring about 25 hours for this image, but after three weeks of clouds, overcast, and fog, I decided to process what I had. In this image, I used only subs with HFR ranging from 2.0-3.0 totaling about 14 hours. Fortunately, despite the modest quantity of data, the image noise was not too bad and I used successive applications of Pixinsight Multiscale Median Transform and Deconvolution on all channels. About 8 hours of good Ha data were used to produce the luminance layer. This rendition is an SHO with traditional Hubble palette color assignments.

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.
