Arp 1 (NGC 2857) and Arp 285 NGC (2854 and NGC 2856)

A two for one Arp special!

An interesting pair of bright spirals emitting jets of material in odd directions compose Arp 285. The right most NGC 2854 has some faint fans of material coming out from either end that don't show up here, unfortunately, even after stacking an hour worth of image data. The sky transparency just wasn't good enough I guess, or maybe there was just too much light pollution. However, you can see the fans coming perpendicularly out of the core of the middle galaxy, NGC 2856, as well as a fainter one at one end of the galaxy.

Face-on spiral NGC 2857 is also listed as Arp 1. It looks to be a fairly normal face on spiral, so I am not sure why it got an Arp peculiar galaxy designation.

The exposure is 7 stacked images, each of which is a live-stack from SharpCap 3.2 of 241 x 2 seconds.

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.
