I have just gotten into photography and I know there are many members on this site that are photographers as well…hobbyist to amateur to professional. I just purchased a digital SLR, and I love the versatility of being able to add lenses, but boy lenses can be expensive. I would love to get one of those high-powered telephoto lenses, but I don’t want to hock my car in order to do it.
Anyway to make a long story short, I found a very interesting article while searching the web today. It discusses a technique called digiscoping. It's perfect for nature photography and seems to primarily be used to photograph birds.

Digiscoping is the technique of shooting with a digital camera through a telescope or other optical device that magnifies significantly.
Also try entering "digiscoping" in a search engine as there are lots of sites on the technique.
