Arp 297

Arp 297, in Bootes, is an interacting galaxy group, consisting of NGC 5752, NGC 5753, NGC 5754, NGC 5755. Along with NGC 2718 and UGC 12158. NGC 5754 is often considered a Milky Way-twin. Note that, although in the same field of view, appearing relatively close to each other, NGC 5752/54 are 200 million light years distant, while NGC 5753/55 are 427 million light years away.

This was an experiment of imaging with a f/12.5 Maksutov-Cassegrain, without a reducer.
I would like to get more integration time on it, as 6.5 hours is much too little at f/12.5

Special thanks to Gary Imm, whose compendium led me to this interesting galaxy group.

edited May 19, 2024:
I just realized from this plate solve (and three other independent plate solves) that this telescope was operating at f/16.3, 2480mm focal length, and NOT at f/12.5, 1900mm focal length, as it claims to be. It was at prime focus with no other optics between the telescope and the camera, except for LRGB filters. I don't know why, and I am waiting for a response from Explore Scientific.
No wonder each individual image looked essentially blank. Imaging at f/16.3 is just a step away from imaging with the cover on (though Hubble and James Webb image at f/20)

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.
