Date/Time of photo
I used a Celestron C9.25 with a Celestron F:6.3 focal reducer in front of a Canon 500D DSLR, autoguiding on the Comet itself. The separate images were stacked using Registax4, with final edits in Photoshop CS4. The exposures were 4 minutes, taken 20 minutes apart between 11:30pm on the 28th, and 3:30am on the 29th.
This is a time lapse movie of Comet Garradd.
