Actually, I have had the same question on my mind recently, and have often
read others discussing using a barlow, but was unsure if they were
attaching the camera to it or if they used it in eyepiece projection. I
would have answered this question for myself if I owned one. I've been
considering buying a barlow, if for no other reason than the fact that it
would give me more magnification options. Now I know for sure how it is
being used with digital cameras and know that it would work just fine for
my set up. Thanks, Chris.
