NGC 6160 Widefield - Galaxy Cluster ACO 2197

This is first light on my new (to me) Esprit 120ED. I picked it up from 'Canada-Wide Astronomy Buy & Sell' back in January, and have been itching to use it ever since. This is a strange target for 640mm focal length, but I could not wait any longer to try it out!

Galaxy cluster ACO2197 in Hercules is dominated by 3 giant elliptical galaxies - NGC 6146, NGC 6160 and NGC 6173, and thought to be at a distance of 126 Mpc.

Of note is NGC 6175 which is a double galaxy - a spiral plus and elliptical. Perhaps I will return here next year with more focal length.

If you like looking for distant galaxies in pictures, there are a LOT more galaxies here than identified in the plate solving information. Take a look at the inverse image - they are easier to spot.

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.
