Comet C/2009 P1 (Garradd) - 23:00hrs, 01/09/2011

After passing M71 in Sagitta, Comet Garradd is now moving past Brocchi's Cluster (the Coathanger) in Vulpecula.

This is a stack of 15 jpegs straight from my camera, taken through a 70mm Televue Pronto refractor. The Coathanger is too big to fit in the field of view of my Skywatcher 200P! It's the first time I've used a refractor for astrophotography and the resulting image is by no means perfect, I seem to have blue halos around the bright stars. The frames were stacked based on the stars which means I've got slight trailing on the comet itself and shows just how fast it's moving. The total equivalent exposure time is 21 minutes.
