EquipmentCanon 20D at ISO 400 with Tamron 180mm F/2.5
DescriptionAfter many days of bad weather, we finally had a decent night to image. Using a manual focus Tamron 180mm lens on a Canon 20D, nine three minute subs were taken while piggybacked on a Paramount ME. The exposures were hardly enough to provide data of the tail but there was just enough to make it visible.
