It's easy when the mount is permanently placed on a pier... So it is only a lens and camera (and couple of other small accessories) to carry out.
I think I may have "before", but with another lens.. .I have to dig into my archive.
Found previous image, from dark(er) site (Seymour), taken on 26/12/2011.
The image is significantly deeper than yesterdays one, despite the much smaller lens.
Canon 100mm f/2.8 at f/4, Canon 400D, ISO800, stack 16x1min.
Position of nova is marked.
