This photo was taken using a digiscoping technique. Digiscoping is a method of bird photography that pairs up a digital camera with a spotting scope. I used our refractor telescope.

One of the problems you'll run into, especially so with lower grade optics, is color fringing, where the edges of objects have a magenta cast or glow. As I understand it this is caused by chromatic aberration: the different colors of light dispersing on different paths after going through the lens. This is common in refractor telescopes, the more expensive apochromatic lens correcting much of it.

These birds were in the trees at the back of our yard, about 80 feet away and 30 or so feet up in a tree top. The original image has quite a bit of magenta/blue fringing and even with many photoshop adjustments I couldn't really get rid of it. Still, I like the composition and converting to black and white retained much of what I liked. Not sure about framing though, originally there was a border around the whole image, then I limited it to just the bottom. They seem a little less boxed in this way.
