Hi Charlie,

I was about 100ft from this fearless fella. The "lens" is actually a Celestron C5 telescope. It is a 1250mm scope used in the "prime focus" mode with an f6.3 focal reducer. The focal reducer gives a wider field of view, and a sharper/"flatter" image but in trade, there is a small reduction in "power" (I think it becomes around 800mm) and a very slight vignetting effect in some situations. The improvement in the photo with the reducer easily outweighs the power reduction. As a "bonus" this "monster lens" can be had for around 5-6 hundred dollars and is incapable of the dreaded chromatic aberration. It is, however, rather unwieldly...like shooting photos with two 3 pound cans of coffee strapped to the front of your camera and it is f-stop fixed at f10 or f6.3 (with reducer). All exposure is trial and error with shutter speeds. The focus is acomplished with a small knob on the end of the scope so, it pays to have a stationary subject. Still, I love it.

Hi Suzan,

Thanks. I believe these are immature bald eagles. I read that they are "all dark with some white mottled in the wings and tail. In 5-6 years their head and tail feathers will turn white, and their eyes and beak will turn yellow".

Neat shots. Its almost as if the eagle was posing on a photo shoot. I'm also impressed with the use of the telescope for getting these images. Good investment a telescope and a long lens.
