NGC 6960 Western Veil and Pickering's Triangle in OSC

To update for the final revision, I did combine (ditched a few of the 120 sec subs) the two groupings, but in this case I used a different protocol in PI. After calibration with the appropriate darks, etc., I actually took the individual calibrated subs and star aligned all together and integrated and then drizzle integrated to get to the final pre-processed image.

(This is the result of 30, 60 sec subs with gain 90 (Unity) combined with 37, 120 sec subs with gain 0. Not sure what I gained trying this (pun intended), but it was an exercise I wanted to try. Really I was hoping to expand the dynamic range in the final image. Not sure it worked.)

Description: After applying some newly acquired processing techniques (or philosophies) to my Eastern Veil project yesterday, I thought that I would revisit the data that I had for the Western and Pickering's Triangle.

In addition, I also had the challenge and hopefully some advantage of melding 60 second and 120 second subs, in a new way, which I had hoped would boost my end product. The 60 second subs were collected at unity gain, but the 120s were at zero gain. Just something that I thought I would try during the sub acquisition, but not planning on merging the two necessarily. In the end, I think that I could see a bit of an improvement in the raw stacked image at the level of background noise reduction.

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.
