Ngc 5899, 5900 Tidal streams and more

Seldom photographed NGC 5899 & 5900 (top) and NGC 5893,5895,5896 (bottom left) in Bootes. N5899 & 5900 are approx. 120 MLY distant. Judging by the tidal stream on NGC 5900, they appear to have had possible gravitational confrontation in the past. N5899 has an interesting “prominence” tidal stream loop stretching up towards the east which appears to be an interaction with what looks like a satellite galaxy (SDSS J151510.91+420334.6). The cropped inverted image (original image) helps portray these features. Very faint and distant galaxy cluster NCS J151456+420852 (estimated distance 3.6 Billion LY) can be seen here located about half way between n5899 and n5900 down just to the right and slightly above the brightest star in the inverted image. The Magnitudes range here from 20 to 22.5 so they are very faint (Credit Bernhard Hubl's website for that tidbit).

NGC 5893 and n5895 at the lower left are estimated to be about 250 MLY distant, while N5896 is estimated at 915 MLY. This group together is listed in the Homberg catalogue as Holmberg 701. The galaxy on the lower right is CGC221-040. The Bright star is a mag 6 star which created a bit of a challenge.

LRGB: L 102 x 600; RGB 18 x 300 each

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.
