Pillars of Pacman

I am fascinated by the "pillars of creation" type of formations near the cores of some nebula, IC1590 the Pacman Nebula is no exception. I had a couple of clear nights but the Santa Ana winds kicked up...luckily no fires started. My guiding RMS never got better than 0.8. In this, I used an SHO image with 70% green removed with SCNR, and blended with an HOO image as I liked what I thought was more "natural" resulting color. Ha as luminance. For the stars, I used a pseudo RGB combination from the Ha, Oiii, Sii data (thanks Uwe!). I used just a tad of Topaz noise reduction settings: low light noise reduction 4 (out of 100), sharpening 0, recover original detail 15, color noise reduction 5. I like the speed and noise reduction of Topaz, but do not like the sharpening features. "recover original detail" negates the sharpening. My processing intention was to highlight the pillars. This was a rewarding image to process...started from scratch 5 times. I am pleased.

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.
