Hi Mike

not photographed a comet before huh?

even a 30 second exposure of a comet will show remarkable movement. So, if you wanted to take an image of a comet, represented as it was in the same fov, your exposures would have to be very short, and therefore, quite unusable.

Comet 3P/Hartley passed by the Double Cluster over about a 2 day period. I imaged the Double Cluster (the image posted) on 1 and 3 Oct, then I started a mosaic of the area 6-8 Oct. Comet moved through 7/8 Oct. So a mock up? Nah.

cheers
Martin
