Title: M16 Revised with Drizzle Integration and better color calibration

Description: The second image revision utilized Drizzle Integration in PI, and the 1st draft was the WBPP integrated result without drizzle. When I initially tried to develop the 1st image, I applied a Linear Fit correction of the drizzle integration and could not get Photometric Color Calibration to work - came out with grossly blue balance. So I gave up on drizzle integration of the first image and developed from there. With the second attempt, I did not employ Linear Fit, instead doing Dynamic Background Extraction on the linked image and then PCC. I think the colors that came out of this PCC color balance are more accurate than the more orange hues that came out of PCC in the 1st draft. Stars were definitely more blown out with the Drizzle Integration, and I ended up with HSV repair to try and fix. This seemed to work better than ColorClip script. These were images taken June 2021, so I look forward to getting a better chance with many more light frames this year.

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.
