17)The comet has a tail of close to 40 degrees now, so I have done a Photostitch of 2 images to fit it within the FOV of my 24mm lens. They were both 2 minute exposures at F1.4, using Canon 20Da at ISO 800. The comet was still visible to naked eye this morning, about half as bright as the Small Magellanic Cloud, Lester Barnes
