NGC 6781 - a planetary nebula in Aquila

I tagged NGC 6781 for imaging some time ago but I wanted to visit it with higher focal length. Now with the EdgeHD at hand I decided to image it.

In the separate frames it looks like a green/blue ball with a red halo. After I stacked the images the halo became even bigger showing some shock-waves coming out of the center. BlurXterminator, GHS and LHE brought out some nice cloud formations. I think that the progenitor star can be seen as well - magnitude 15.

I found the following information for this object - found by William Herschel in 1788. Distance from the SUN - 1500 light years. The apparent size of the object is 1.9x1.8 archmin. It is believed that we view the nebula pole-on so its true shape may be even more intriguing.

I am in love with this image and the EdgeHD.

CS,
Ivan

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.
