Male prothonotary warbler taken at Fort DeSoto State Park along Florida's Gulf Coast.
Bill of the Birds: August 2006
I did not take another digiscoped image until I was in Florida three months later (to see my beloved
Pittsburgh Pirates
play the hated Cincinnati Reds in a spring training game.) My second subject was a tired migrant prothonotary warbler male in the grass at Fort DeSoto. On this day I took many digiscoped bird images--nearly all of them bad. I could not get the camera lined up properly with the spotting scope eyepiece, so I got black vignetting around the edges of my images.

A bit of research on the Internet gave me a solution to the vignetting (digiscoping was catching on worldwide): two plumbing rings, one fit onto the camera lens ring, one set inside the scope's eyepiece and the camera was centered every time. The down side of the plumbing rings was that the one resting loosely inside the scope's eyepiece would cooperatively fall out every time I hoisted the scope onto my shoulder. I lost at least a dozen rings this way.
