NGC 5613 - Arp 178 in Bootes.

Here's one I took a while back and just got around to processing into something reasonable. It's an odd one, ngc 5613 through to ngc 5615, again from Arp's catalogue of peculiar galaxies. Arp 178 in Bootes is catagorised as having 'narrow counter-tails', - not really sure what that means. ngc 5613 is the small spiral galaxy, actually a 'ring' galaxy, at the 7-o-clock position relative to the central galaxy, ngc 5614, which is a SAab pec spiral. ngc 5615 is the tiny galaxy at the 8-o-clock position to 5614. It is listed as mag. 17.8 and 0.1' size. 5613 is mag 15.5, 5614 mag 12.5. Notice the tiny chain of galaxies about 4' from 5614 in the 4-0-clock position. They are not identifyable on my charts. There are many other faint galaxies spread across this image.

The interesting thing about Arp 178 is that each of the 3 galaxies mentioned has a different redshift; the point is are they connected? Arp clearly thought so and his atlas image does appear to show a connection.

It was examples such as this that led Arp to suggest that redshift/distance relationships should be re-evaluated.

My image was taken in May using 30 x 120 second exposures through my 10" f4.8 reflector.

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.
