Messier 27, also known as NGC 6853 or The Dumbbell Nebula is a planetary nebula in the constellation Vulpecula. It is 1.360 light-years far from Earth and is estimated to be 9.800 years old.
The central star radius is among the largest known for a white dwarf. The nebula is expanding at about 31 km/s and its residual life is estimated no longer than 14.600 years.
The central region is marked by a pattern of dark and bright knots; the heads of these knots have cusps which are photoionization fronts.
It was the first such nebula discovered, by Charles Messier in 1764.The picture was taken in Cordenons, from my home garden under a sky Bortle 6-7 (SQM 18.5-18.75), using a ZWO ASI2600MM PRO camera with a Celestron C11 Edge on my SkyWatcher EQ8-R Pro. I programmed sessions at ZWO ASIAIR PLUS @zwoasiIt’s the sum of 54 RGB shots of 180”, 37 OIII shots of 600”, and 27 H-alfa shots of 1000”.I used RGB shots for stars and HDR elaboration due to thigh luminance in the central region.

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.
