Sh2-248 [plus Sh2-249] -- The Jellyfish Nebula in H-HO-O

Shooting Oiii with Moon illuminated greater than 50% is kind of critical. But after such a long time of bad weather conditions I wanted a SHO image no matter what! Unfortunatelly, after 4 subs in Sii a Windows security update crossed my plans...The Sii master file does not look great since the satellite trails and stacking artefacts disappear only with more integration time or subs respectively. So here is the H-HO-O rendition of the Jellyfish.

The Ha can be found here:

Thanks for watching!

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.
