Fireworks Galaxy & star cluster NGC 6939

I started this image on 6/12 with my Sky Watcher 190mm Mak/Newt, but it is out of commission as the lens/camera holder on the focuser is broke and I cannot find a replacement or replacement parts anywhere. I have even email Sky Watcher USA. So I put my ES 127mm back on my mount and finished this up. I was pleasantly surprised when NGC 6939 showed up in my image, so I did not crop this too much.

The Fireworks galaxy is fairly dim, with lots of nebulous objects and centered in a rich star field. It is estimated to be 40,000 light years across and over 20 million light years away. Nine supernovae have been observe as of March 2009, so the number could be higher, which is where its name was derived.

The refractors!

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.
