Hi All, See http://www.astromania.co.uk/174P_20180104_1915_PCarson.jpg for my 48 minute exposure of 174P Echeclus earlier this evening 2017 Jan 4th. It appears to be showing a faint near circular "shell". Is anyone else seeing this? My other 174P images are here http://www.astromania.co.uk/comet_174p_echeclus.html Peter Carson
