Arp 310 and 311 in Draco.

I enjoy hunting down these faint Arp galaxies and this one is very interesting. These can be found high up in Draco. There are 2 Arp's in this field. Arp 310 is IC1259, a close pair of galaxies, whilst Arp 311 actually includes Arp 310 but adds IC1258 and IC1260. IC1259 is the more Northerly pair of pec galaxies, coming in at mag. 15.2 and mag. 14.3, both are pretty tiny, sub arc min. examples. IC 1258 is a spiral galaxy of mag. 14.8, whilst IC1260 is a compact galaxy, mag. 15.7. The distance to these Arps is a staggering 375 MLy.

Halton Arp hinted at a bridge of material joining IC1259 and IC1258 but there is no sign of it in my image.

What Arp didn't comment on and what I find more interesting is the presence of at least one quasar very close to IC1259. I've anotated it as Q9.6, about 2 or 3 arc mins N of IC1259. A distance of 9.6 Billion Light Years places this quasar a very, very long way from IC1259. I've also anotated several other quasars in the image, most of them with even higher redshift. You may have to take my word for it but they are there! The one at d=5.3 BLy appears to be not a point source as most quasars are.

There are additionally hundreds of more distant galaxies spread right across this image, too many for me to even begin to identify.

My image taken on a night of exceptional clarity last month, is the result of 30 x 3 minute sub exposures through my 10" f4.8 Reflector.The camera was a SXH9C OSC ccd camera, with an IR/UV filter. Image acquired using AstroArt3, processed in AA3 and PixInsight.

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.
