But no pictures. Is this something that someone who is a klutz do successfully?

I have an 18mm Radian that has the proverbial drop syndrome. Lift it out of the case and it slips all the way up. But the views are spectacular and I'd hate to do something BAD to the eyepiece!

Just follow the instructions, they are simple and there is nothing in the proceedure that is difficult. Just don't touch the lens while doing it.
