Keenan's System - Arp 104 - NGC 5216 and NGC 5218

I spent many nights in April imaging this system hoping to capture the tidal bridge of material between NGC 5216 and NGC 5218. Imagine what the night sky would look like if our Earth orbited a star in this bridge with 2 galaxies so close! Of course with my luck they would both be in the southern hemisphere...

I still find this amazing that I can image these galaxies in a bortle 8 sky with a telescope I bought in 1983 and a budget astro camera with a clear UV/IR filter.

It just blows my mind.

NGC 5216 is listed as magnitude 16.14 in Stellarium. According to the Aperture Photometry script in PixInsight, there are stars down to an apparent magnitude 20.91 in this image (if I am interpreting the result correctly).

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.
