M27 Dumbbell Nebula

I have decided to leave the C11 on the mount all summer, and target fairly bright objects. I did not have a good M27 in my portfolio, so it made my 2023 list.

M27 or The Dumbbell Nebula was discovered in 1764 by Charles Messier, and is thought to be the first planetary nebula discovered. It lies at a distance of 1,200 light years and has a magnitude of 7.5. Its central star is a white dwarf with 0.05 times our sun's radius and 0.5 times our sun's mass.

The most difficult part of processing this image was that there was too much signal. The core came out white in my earlier versions. I dimmed the stars within the nebula to make the details more visible.

Hope you like it.

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.
