Take a look at the new digiscoping adapters by Radian. I had an opportunity to tinker around with both adapter sizes and they should greatly simplify "the digiscoping dilemma" for a lot of people. For a bracket-based adapter, they are very small and lightweight. Best of all, they are relatively inexpensive compared to a lot of other “universal” digiscoping solutions out there. One of my co-workers took the time to test the adapters out of different spotting scopes, so we’ve even got a list of scopes that they’ll work with. Just remember, your digital camera has to have the standard tripod thread in order to attach it to the adapter. Still, I prefer the filter thread-based adapters, but if your camera cannot be converted to one of the conventional filter thread sizes, then this is probably the best way to go!
