Monkey Head Nebula - NGC 2174

Spent a lot of time on this to try a bit more processing in Pixinsight. I typically do all of my preprocessing in PI an then split my postprocessing between PI and PS. Been working my way through Adam Block's great tutorials (thanks Adam!) and trying to pull in some of the newer processes into my tool box. I'm pleased with how this came out but for the amount of integration I had to work hard to deal with noise. I like to drizzle 2x on most of my images so that I can process on a smaller image scale but found that many of the PI processes that otherwise would remove single pixel noise weren't working because the drizzle step made these larger in scale and thus operating on an alternate frequency space - one shared with larger structures. Once I went back and worked on the original scale I was able to much more effectively work with this noise. This is also likely the source of the larger scale mottling that I had been getting with some of my images. Not really necessary to drizzle at my image scale, just always liked the increase in data. Force of habit from my old QSI683.

In this image I used Ha as lum, tonemapped each channel with StarNet and overlaid the stars afterwards. I used an HOO process on the stars to get more realistic colors, SHO for the neb.

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.
