Sh2-155 A Dusty Cave

This one has been quite tempting to process, as seeing conditions where
not ideal during the two nights when I captured the frames.
It was a good opportunity to try some new processing methods I have been
thinking about for a while. As most of the frames showed somehow blurry
stars, despite being well focused, I only used about 30 frames LRGB for
creating the star image. I processed the image until I was satisfied with how
the stars looked like and then used StarXTerminator to separated the stars
and dumped the nebula image.
Then I did the same, using all LRGB frames, again used StarXTerminator and
this time dumped the star image and kept the nebula image.
After processing them separately, the star and starless image were combined
and finally processed in Photoshop, where I also added the starless signal from
the Ha frames I had captured. I subtracted the red signal from the Ha signal and
blended it into the LRGB image.
Turned out to be a good method to "rescue" the stars when seeing conditions are
not on your side and I'm quite happy with the result.
Hope you like it.

CS,
Michael

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.
