Sh2-200, Bear Claw Nebula

I didn't find a lot of information on this faint planetary nebula. From other sources, this planetary is supposedly pretty old. It's reasonably large (~6 arcmins) and does give up some details, but it's REALLY faint. In this OSC attempt of 5.5 hours @ f/2.2, each sub exposure is completely devoid of any hint of nebula. After integration, most of what is visible (beyond stars) is OIII. Some of the outer faint hydrogen is weakly visible in the rich field. What I find interesting about this nebula is the cleared out ring gap, as well as the square cleared interior region of the nebula. An interesting geometry...

This object would need a LOT more time to do well. Maybe this will be a work in progress for another day. For now, it is what it is.

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.
