FWIW, final night with the RASA 11 setup. Comet activity seems a bit more interesting closer to its nucleus, so I've set up the C14 hyperstar this time with a fullframe sensor. The field is only slightly smaller. and there is a slight increase in resolution (I've already imaged with the setup and I am happy with the results!). I've overstretched this image to highlight the plasma tail and nuclear streamers. This has adversely over stretched the fan shaped dust tail leaving an unnatural looking feel. Best to look at the comet-aligned image to see the details I have lost in post. Olbers has thinned out a bit when looking at the plasma tail yet the comet is still an easy find in binoculars.
