A closer look at M27, the Dumbbell Nebula in Vulpecula

The Dumbbell Nebula (also Apple Core Nebula) was never really on my bucket list for two reasons. On the one hand, it is a very common target because it's a large and bright planetary nebula, well suited for smaller telescopes and beginners. Of course, I also tried to photograph M27 earlier with more or less okayish results. But on the other side, it also is a pretty challenging target because of its bright core and very faint outer shell. Thus I thought it could be too disappointing when I tried to photograph it at f10 in Northern Germany, where we have too few clear nights, and I may end up with a limited dataset.
However, I did not try to photograph a nebula with my EdgeHD 8 yet and thought that M27 would be an excellent target to test this out. The core is bright enough, so even if f10 would be too slow, I at least was awaiting a decent result. And I must say that my expectations were exceeded - with just 4 hours of total integration time, I now look at a result I did not expect. The core was very bright, and I had to bring it down a bit, but even parts of the outer shell are well visible already. Of course, there are much deeper images with much longer exposure times, but this is what you can get within one night and some tweaking in PixInsight and Photoshop. I'm glad I tried this one.

Description: I just learned about the new star-reducing method from https://www.youtube.com/watch?v=oRe7iP4QU1k and tried it on my processed image. It works super nice IMO and thus I had to update the image :-)

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.
