This picture of M57 was taken from the observatory dome with an icy wind blowing in the opening, soon after dusk twlilight with Lyra and Cygnus still reasonably high in the western sky. The only problems being 1. car headlights and 2. a buffeted telescope. I couldn't get any 30-second shots without trails, so I de-trailed them all (phew!) and stacked the best 16 of them. Despite the de-trailing artefacts which appear as streaky noise you can easily make out IC 1296 the 15.1 magnitude spiral galaxy to the right.
