M27 - Dumbbell Nebula

M27, the Dumbbell Nebula, was the first planetary nebula to be discovered (1764), though it wasn't recognized as part of a new class of objects until William Herschel coined the term "planetary nebula" twenty years later. Usually images just capture the inner bright part, which looks like an apple core or (if a longer exposure is used) -- kind of a dumbbell? But if you expose much longer with H alpha and OIII filters you see there's more to it. It really looks more like a bat with the extended emission.

I've been working on this off and on, and I'm not quite happy with it yet -- the HDR toning has flattened the core, and the wings could use some more OIII time.

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.
