SH2-117 - (North American, Pelican Nebula Mosaic)

Photographing the plane of the Milky Way Galaxy is something I could only dream of as a kid. Containing emission nebula, dust lanes and vast star forming regions, Cygnus is full of rewarding targets. In 2020, the Gaia astrometry spacecraft estimated SH2-117 to be 2,590 light years from Earth, and about 140 light years across its HII regions.

I incorporated data from my previous upload of the Pelican Nebula, and combined it with newly captured lights of NGC 7000. Luckily, using the mosaic scripts and modules in Pixinsight turned out to be a fairly straight forward process.

Unfortunately, all the UV / IR data I captured was unusable, due to the fact that it was so grainy. When I added it to the processing, it gave depth to the photo, but really blurred the details. In the end, it was only used for the stars. I do have an Optolong L-pro filter in my filter wheel that I may try next so as to not waste so many light frames, (I hate that). Hopefully, that will knock out some light pollution without harming star color.

I apologize for the size. Reducing it degraded the photo to a point which made the image not worth posting. I'm still working on the best way to handle that part of the post processing.

Comments, suggestions ?

Thanks for looking.

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.
