M15 Pegasus Cluster

Revision title: M15 reprocessed

The final image is a composite of 59 x 10s subs, 16 x 20s subs, and 11 x 30s subs on 9/22/2019 shot with a Lumicon deep sky filter and 10 x 5s subs, 10 x 10s subs, 10 x 15s subs, 10 x 20s subs , 10 x 30s subs, 10 x 45s subs and 5 x 60s subs unfiltered and monochrome for luminance. shot on 9/20/2019. All together, there were 161 images at an average exposure of 18s. Stacking produced artifacts at field edges that had to be cropped out; the actual image uploaded has a resolution of 2071 x 1325 pixels. Sky transparency was fair, seeing was poor to fair (typical of Denver) and moonlight did not interfere at the times the images were acquired. All images were unguided. The wind was problematic on 9/22/2019 so I had to review all images by hand to cull those that were too compromised by wind shudder, leaving the image counts as reported above. The total integration time was 0.8 hours.

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.
