NGC6164 and NGC6165 - The Dragon's Egg

NGC 6164 and NGC 6165 - The Dragon's Egg in HOO. Taken over 2 nights during a 90% moon. Nonetheless, it came out fairly well. NGC6164 and NGC6165 are emission nebula about 4 light years across which was created by the luminous star you can see at its centre. This is an O-type star about 40 times the size of our sun and is expected to go supernova in the next 3 or 4 million years or so when it burns itself out. The nebulae were originally thought to be a planetary nebula but it's not the result of shrouds of gas emitted by dying sun-like stars. Instead, it is thought that the nebulae were created during an earlier phase in the stars life cycle. The Dragon's egg is 4200 light years away. The name was given to its egg like shape and its proximity to the famous fighting dragons of Ara. Dragons have to fight over something i guess.

Description: I noticed rings around the stars in the original version which I found was the result of convolution. I decided to see what the image was like without convolution and got a much more pleasing result - to my eye at least. I've also tweaked the contrast and saturation. Hope you like it. Happy for any comments/suggestions.

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.
