NGC 6217 (Arp 185) and UGC 10509

Acquisition type: Lucky imaging

I took advantage of a few days with pretty good seeing to collect 7 eight minute images of this pair of galaxy groups. NGC 6217 is only 25 million light years from us, while the grouping around UGC 10509 are 10 times more distant at around 250 million light years.

The faint broad outer arms of NGC 6217 (Arp 185) are just becoming visible above the light pollution in my suburb. The combination of illness this last winter, bad weather and COVID this spring and onward have robbed me of visits to dark sky sites since last early fall. I am sure those outer arms would really pop under a dark sky.

Each of the 8 minute images used to produce this image was a live stack of 240 two second subs.

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.
