NGC 281 Pacman Nebula

My second clear night at 1600m in Styria was dedicated to Pacman (after moon setting) - a windy but highly transparent sky (the wind was apparently no problem for the MGEN). The image was cropped to one-half size to show more nebula detail. First time I tried some star reduction using Fitswork - hope the artifacts are not too visible...

Edit: Bad weather for weeks ... reprocessed the existing stack with more subtle star reduction and tried to combat noise using Starnet++

Re-edit: Yet more bad weather for months :-/ ... did a fundamental re-stacking and reprocessing of the original data using my (hopefully) somewhat improved processing. No star reduction this time. Indeed, there was more information hidden in this data :-).

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.
