I have one eye (left) and although I've tried many times, I can't get on with telescopes. I use various binoculars with too many problems. If you go for a pair which gives a bearing, as one pair of mine does, ensure it is in the correct side! My bother has a pair with it in the wrong side, for me, and I find them difficult to use. I would not remove the side not being used as I find holding them with two hands is the best way on all but the smallest type. Also they are then available to crew members if required.
