This image covers the area between LBN711 (left) and LBN707 (right). I initially wanted to center the image on LBN707 but once I noticed the pair of interacting galaxies half way to the left of image center, I decided to leave the composition as it was. The interacting galaxies are NGC935 and IC1801. Together they are also known as Arp 276.

There are a lot of background galaxies in this one. Be sure to download the full resolution image to soak them all up. The background is a bit on the noisy side. I'll rework this to see if I can improve on it.

Other notes:
For the first time in ~5 years, I did some visual work while my imaging rig was doing its thing. Between frames I was cruising the sky with my 10x70 binoculars and it was a blast. The highlights were the Helix nebula and Barnard's E nebula right next to Altair.

Last time I noted that the Go-to on my new mount was not working. I suspected it to be an electrical issue and I was right. After I resoldered the electrical connection, go-to functionality was fully restored. This saved me a great deal of time as finding these two nebulas without go-to would have taken me an easy 10 minutes. With go-to, these nebulas were properly centered in 10 seconds.

I had one more image on my to-do list for the night, but I didn't feel all that well, so I packed up at 2am.
