Fireworks Galaxy (NGC6946) and Open-cluster (NGC6939)

This is probably my favorite image from galaxy season this year. I really like the framing with the fireworks galaxy and the nearby open cluster along with all the background stars. Sometimes galaxy images with narrow fields of view feel a bit lonely to me when there aren't a lot of stars in the frame. Of course, the fireworks galaxy itself is relatively small for my rig (about 300px wide I think) and I don't see a much of the blue in the spiral arms, but it feels like there is a lot of activity in the picture. I even quickly noticed a small background galaxy near the open cluster (PGC64824) that is quite visible.

I took a new set of dark images for my camera too for this image; it has been a year since the last set, and I think the new set helped take out more bad pixels and gives a little lower background noise than the old ones do. I suppose it makes sense that the CMOS chip ages a bit with use.

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.
