NGC 2174 - Monkey Head Nebula

NGC 2174, the Monkey Head Nebula, is an emission nebula in Orion.

Processed in Pixinsight using Normalize Scale Gradient script followed by integration of Ha, Sii, and Oiii masters. While my notes are a little off, I believe the following process was: Dynamically Cropped, DBE'd, ColorCombined, and stretched with Masked Stretch. Followed by Background Neutralization, adjusted with ColorSaturation, CurvesTransformation (Contrast, Hue Shift), SCNR'd, then another few sets of CurvesTransformation (Hue shift and saturation).

This is my first narrowband image and I am pretty pleased how it turned out. This version is significantly trimmed down to fit within my Astrobin file size limit. Now, guiding 10 minute subs on a guidescope did cause a terrible number of lost subs, but let's just chalk that up to a learning experience. At some point in the future maybe I can also try some RGB stars but I'll save that too for another day.

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.
