Project: 0025

If anyone has any idea how I'm getting these weird diffraction spikes please let me know. I'm not seeing them with any other target.

During the first two nights of this project I came across a problem with a artifact in my images. I know the artifact from the film industry and I know there is very little you can do to fix it in post. After some research I learned that the artifact is caused by too much UV light. So I ordered an UV-filter and the problem went away.
Unfortunately, I wasn't able to salvage any images from those first two nights.

I was still very much searching for the ideal sub-length making the project too complicated.

Regarding the editing: I'm still looking for a way to not over process the background. And to avoid what looks like macroblocking in the color channels when the signal is almost zero.

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.
