NGC 6781: A Planetary Nebula in Aquila

NGC 6781 is a striking planetary nebula in the constellation Aquila that is seldom imaged. Visually, I can verify that it's disappointing, even in a 12" Dob at a good dark sky site, so I think few people get the idea to image it. However, it's a real stunner photographically. NGC 6781 is only 1.9 arcminutes wide and shines at 11.4 magnitude overall, so it's best suited for long focal length imaging.

This LRGB image combines 7.7 hours of integration time over three nights, and the skies were very steady. Luminance was taken binned 1x1 in 450s subs (0.55"/pixel), and color was taken binned 2x2 in 180s subs. The seeing was so good that the color frames were undersampled at 1.11"/pixel.NGC 6781 is a striking planetary nebula in the constellation Aquila that is seldom imaged.

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.
