Digiscoped Image of Peregrine
This image was shot with the same camera as the side-by-side thumbnails below — the ones that look like oil painting details. The difference is this was taken through a telescope that increases the effective focal length by 6.4 times. The camera's 420mm lens is converted to a 2,688mm lens. Unfortunately the focus is not quite right. Practice might help.
This Peregrine Falcon was perched on the north-west corner of the G.M. Building. The photo was taken from Gapstow Bridge just south of Wollman Skating Rink. The approximate distance to the falcon was 1,200 feet or 0.23 miles.
