Elephant Trunk in SHO

Well the months long rain and clouds finally gave way to four great nights in a row! Seeing was some of the best I've ever had at home, and it was only 80%relative humidity, which is definitely the driest I've ever seen haha. I could vaguely make out the Milky Way, and it was made abundantly clear how little sky we have without a bad light dome. There are bad light domes immediately north and south of home. I grabbed a few nights of data on the Elephant Trunk. I started getting data on the Veil Nebula the last night and plan to get more data on it next week if the forecast holds.

It was also quite nice as my neighbor met another astronomer/astrophotographer that just moved to the area, so we spent some time getting to know each other the first night. The last night we did some visual observing and tried playing around with his planetary camera. The mosquitoes were out of course, but it's been so long that we just toughed it out.

I processed this image different than any previously to try some different things out. I'll probably have some different revisions up later, but this first one I was going for a softer image. Instead of taking the stacked SHO images, combining them first, stretching, and then dealing with the noise, I did a denoise on each filter's stacked image first and stretched each filter's image prior to combining. It did lose some details, but I got the softer image I was hoping to get. I would love to hear your thoughts.

All stacking and processing done in Affinity Photo.

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.
