Ghost of the Moon Nebula (NGC6781)

This object caught my attention as one of the many faint planetary nebulas I've never previously seen or imaged......and with Halloween right around the corner, and given it's name , I thought I'd give it a try! :-)

NGC 6781 is aptly named, appearing as a extrremely faint, ghost like disk of light in my brief 10 second exposures when first attempting to find and aiign the object for imaging. (Brightness is stated at 11.4 for the nebula, with the central white dwarf star at ~16.8 magnitude)

This planetary nebula lies a few thousand light-years away towards the constellation of Aquila, and is approximately two light-years across. Within NGC 6781, shells of gas blown off from the faint, but very hot, central star’s surface are expanding out into space. These shells shine under the harsh ultraviolet radiation from the parent star in intricate and beautiful patterns.

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.
