Already shot this planetary nebula using an 80mm refractor, but it seemed the perfect target to test my new Celestron OAG in combination with the Edge HD 9.25. Lots of stars in the vicinity and since I don't have the reducer, not too big so it would fall of my small sensor (ASI ZWO 183 MC). I was pleasantly surprised to see that guiding went OK (although getting round stars at 2350mm of FL is pretty challenging!), showing lots of detail already after only 2h of data. Overall happy with the OAG's first light.

The Dumbbell Nebula (M27, NGC 6853) is a planetary nebula located in the constellation of Vulpecula, at a distance of about 1300 light-years from Earth. It was the first planetary nebula to be discovered. Charles Messier included it as M27 in his catalogue of deep sky objects in 1764.

Planetary nebulae are the remains of stars similar to our Sun. When they reach the end of their life cycle as evolved red giants, they expel their outer gaseous layers to form the nebula, which is then heated by the hot core of the central white dwarf. This will be the fate of our Sun in roughly five billion years. The central white dwarf in M27 is really just the core left from the original star, and it is extremely hot.

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.
