I've found that when I'm using this telescope (monoscope? monocular?) I often can't focus because I'm too close. I read the description but I think I underestimated the distances I will be using it. It's a great little tool too - light weight, compact and comes with a nice case. It wobbles a little when you use it with one hand, but stabilize it a bit with the other hand and it works fine.
