If you want to see something new in nature!
I handhold my unthreaded-lens cam to scope, and have been fairly happy for 2+ yrs of same. Had heard of putting some kind of bushing (like a small doughnut shape) into the rubber eyecup to center and hold the lens, but never got so ambitious as to try to make one - seemed too difficult. But last week I got the 5x telephoto from Eagleeye UK and with it a 37mm to 30mm adapter ring for my Sony Camcorder lens. I found the 37mm side of adapter fits almost perfectly into my Kowa 32x ep rubber cup, so I just wound some black electrician tape around the small inner hole making an extending flange and voi-lah, the bushing. I only needed to add a little more tape around half the outer dia. to lift the camera lens perfectly up to e.p. center. Since threaded adapter rings come in many sizes, I thought this might be worth passing along to other less than handy fabricators. I tried it out in the field today, and the bushing stays put inside the rubber cup through carrying over rough terrain, makes the shot quickly centered, and seems to even steady it vs. hand-positioning only.
