digiscoping
Mike's excellent digiscoping blog describes a new scope & camera unit by Nikon that will enable you to get into digiscoping on the cheap (well, relatively cheap). You can see details on Eagle Optics' site. I have some concerns about the small aperture of the scope (50mm rather than 70, 80mm or more). On the other hand, the total unit is very compact and should be easy to lug around, depending upon the tripod you pick.
