There is only a night or two more to image comet 21P passing NGC 7000 the North American Nebula. See Nick James’s Observing Challenge https://www.britastro.org/node/14384 The skies over much of the UK are forecast to be good. Earlier this morning I managed this image using my DSLR and 200mm lens. https://britastro.org/node/14507
This conjunction has certainly encouraged a lot of people to have a go at imaging this (currently) rather puny comet. Denis Buczynski has just updated our image archive and you can see the results for 21P here.
