*** Update ***
I added 4 more hours for a total of 5 hours. Wish I could of gotten more but clouds shut me down for 2 1/2 hours. I am grateful for what I got.

It has been about a year since I was able to make it out to the HAS dark site to do some imaging. It was really good to get out again. Unfortunately, the weather did not cooperate, and I was only able to get what I considered the minimum to even create an image. I usually try to get 7 hours our more on a target. Not sure when the next time I will make it back out to the dark site so I decided to process this data to see what I could get. This the first time I tried BlurXterminator. At my image scale, there is little detail in these galaxies to begin with but what I found more useful with that tool is that I could increase the size of the RGB star halos to match the size of the luminance stars better. That was really cool. In my starless processing part, I have found some instances where StarXTerminator provided better results and in other cases StarNet2 gave a better result.

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.
