NGC 6951, Barred Spiral Galaxy

Small barred spiral galaxy, obscured by intervening Milky Way dust. Color camera and IR cut filter. The galaxy is reddened by dust, and the camera didn't pick up much color variation. This image resolves a ring of bright star clusters around the central core (if you zoom in), very cool. Accumulated images over four nights. Really just experimenting to see how much the extended integration time would bring out the fainter ends of the arms. Didn't crop the image to show the surrounding nebulosity.

Half way through this project I acquired a ZWO EAF auto-focus module. It's mounted with a Buckeye Stargazer 3-D printed bracket, not the ZWO aluminum bracket. So, anyway, half of the exposures are manually focused, and half are auto-focused.

The above acquisition details include every exposure. The final image used
240 (of 280) frames x 300s @ Gain 200 @ -10C = 20h 0m exposure time

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.
