M-27 Dumbell in HOO with RGB Stars

This has been a difficult year for my imaging efforts... lots of poor weather in the Southeast combined with scheduling conflicts which prevented me taking advantage of some clear evenings. The result is that this is the first image I've finished since January.

Just came into posession of a new (to me) ONTC 8" f/4 reflector - a great scope! This is my first light image with that configuration. Had some problems with getting the back focus correct for my Skywatcher GPU coma corrector, but that just meant that the corners were not as good as they could be. Fortunately BlurXterminator took care of some of those problems.

My first time attempting to image the Dumbell nebula - there's so much detail in the center of that nebula that typically gets blown out by over exposure. Studied the HDRMT and LHE processes on Adam Block's website and tried a few different ways to use those - I think it helped bring out some of the details.

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.
