As an experiment I tried to image the comet through an ETX 105 with a Canon D550 (12th July 2020 at 01:54UT). As there was no tracking, I had to keep the exposure short at 2s and used a high ISO at 6400. It does show some structure, a bit like, but not a good as, Paul Able’s drawing from yesterday at https://britastro.org/node/23148.
