Tele Vue-85: Portable, Powerful, Photo-Visual APO

Imaging a rare celestial event requires advanced planning, the right equipment, and often a lot of post-processing.  Tony Cook traveled from the UK to Paphos on the southwest of  coast of Cyprus (we suppose for the over 300 sunny days a year) to image the 2004 Transit of Venus with his Tele Vue-85, Coronado SM60 hydrogen alpha filter, Canon 10D camera, and Losmandy GM-8 mount.  The 85’s optical capabilities and airline portability often makes it a favorite for amateur astronomers chasing down rare events like this.
