This comet and C/2006 OF2/Broughton are the two brightest comets available for imaging at the moment at magnitude 10. I decided to try Christensen as it was well placed directly above the house near the constellation Cepheus. The evening looked good to start with, cold and clear skies all around. I was set up by 8.10UT with the Canon 350D and Equinox ED80 setup. I had intended on taking an hours worth of images, but had forgotten the intricacies of setting up the dastardly piece of Chinese gadgetry that is the timer remote release. Having failed to remember NOT to use the numbering sequence, but instead set the number of exposures to infinity I happily left the whole setup whirring away and returned to find it had only taken 12x 1 minute exposures - AAAAARRGH !!! Fortunately cloud had rolled in anyway so I would have been foiled by the atmosphere in any case. Thinking it was a waste of time I ran the 12 images through DeepSky Stacker to see what showed up and to my amazement there was a tiny fuzzy green blob sitting amongst a rich starfield!!! Green fuzzy visible just to the left of centre........
