There's a couple of galaxies just out of my fov. Under the galaxy bottom right, NGC 680, is NGC 678, which is very alike to the hamburger galaxy part of Leo's triplets. A shame I couldn't fit it in. NGC 697 lies off to the right at least another fov away. I chose these 3 galaxies for their diversity.
I took this on the 10th of October and going by my notes it was a dewy evening with a thin veil of mist in the air. I remember needing the hair dryer a few times.
