M97, the Owl

I'll admit that shooting this target with a 94% moon out and at nearly the same R.A. was not a good idea. My first clue that I should have gone to bed early was the overwhelming background glow in the 240s subs I took with my Moon and Skyglow filter. I quickly switched to the L-e-Nhanced filter which was better. I started processing the 3 hours of subs this morning only to find that nether Pixinsight, nor DSS could stack any of the data. So I stacked 15 of the 300s subs in Photoshop to get this.

Description: Finally got Pixinsight to align this data. Now the red rim shows well enough to see the hole at the top of the Owls face.

Set Star selection noise reduction to 10, with matching set to Octagons and went from nothing aligned to everything aligned.

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.
