On the night of October 1st/2nd, 2010, Comet Hartley 2 made a close approach to the Pacman Nebula. I was fortunate to have great weather and devoted my whole night to imaging the get together.
Technical: 286 minutes of exposure (44×60 sec, 34×120 sec & 58×180 sec @ ISO 1600,) TV-85 at F/5.6, IDAS-LPS, Hutech Canon XS. (This image was also used in an online article at Sky and Telescope’s website, which is here: http://www.skyandtelescope.com/observing/objects/comets/102632669.html )
