I have a Swarovski spotting scope and I've seen ads for using it with a digital camera.
Do any of you use this ? Or is it to inconvenient?

done it several times. while they make an adapter to fit some cameras so they mount right up to the scope, i always just sort of hold the lens up to the eye piece and click away. sometimes works sometimes doesn't. really interesting if you hold the camera up to the night vision scope
