Star Cluster NGC 6823 in Nebula SH2-86

I finally removed my C8 from my CEM25 mount. This mount was repaired after I let it blow over several months back. Since then, it just could not track well enough for the C8 at 1260mm of focal length. I have relegated it to much shorter focal lengths with lighter weights.

I purchased a used GEM45 to carry the C8, and hopefully my 120ED (once I get a dual saddle). This mount does a much better job tracking, and I discard fewer subs due to star trailing.

The sky is still clouded with smoke from time to time so it took many nights to get enough data for this shot.

The open star cluster is NGC 6823, and the emission nebula is SH2-86. There is a small reflection nebula NGC 6820 nearby which was visible in my RGB data, but reflection nebula and my skies don't get along so I did not try to include it in the final 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.
