NGC 6845 — Telescopium Galaxy Quartet

NGC 6845, PGC 63978, PGC 63979 and PGC 63986 form an interacting system of four galaxies (quartet) in the southern constellation Telescopium. At 300 Mly distance, the galaxies appear small (around 1 arcmin) and also dim at magnitudes 13.10, 14.89, 15.83, and 14.56. If they were closer I'd imagine they'd form a quite a spectacle and garner substantial interest. Below shows a 7.8 x 6.1 arcmin crop.

The luminance data, from the RC10A, pre-dated some improvements in collimation that I made. So I ended up cropping off a major part of the image (originally the galaxies were centred in the capture frame). The RGB data comes from the RC8. There were 16 sessions of data capture (luminance and color), from August 2021 to May 2022.

The bright star is (unresolved) double star HD 189307 and is 6th magnitude and, hence, not visible to the naked eye from my outer suburban site (Bortle 5).

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.
