Update 20130303 - Some better views of Lemmon tail, using the ED80mm and DKM51 and the DSLR with a 300mm lens, both tracking with the telescope.

Better tail views achieved with DMK51AS 99x10sec images

Update 20130220 - An image of C/2012 F6 via Itelescope T9 90sec exp some imagej work.

Now that I know where C/2012 F6 Lemmon is. I have been zooming in using a DSLR and my Telescope. Unfortunately my night sky is not dark enough to get the long flowing blue Ion tails.
