I used this adaptor on a two different spotting scopes, a telescope and a binocular with a digital Cannon Powershot A530. With trial & error I obtained adequate d-pictures at distance. A strong stable tripod is recommended. Remember to turn off the automatic power saving on the camera.
Pros: Good adaptor for digital scopes
Cons: Instructions could be better
