M97 in HOO

Messier 97, affectionally known as the Owl Nebula, is a planetary nebula in Ursa Major which is approximately 2000 light-years from Earth. It was discovered by French astronomer Pierre Méchain on February 16, 1781. Current estimations date it to be around 8000 years old.

I was finally able to collect some OIII data but not under ideal conditions as seeing was below average and the moon was around 75% illumination. Given the few clear nights I have, I had not much of a choice so I collected a lot of OIII exposures and had to toss out over 60% of them and just use the best of the lot.

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.
