I have a sense the focusser might slide at elevation under heavier loads. I'll test that sometime. But it looks like a little modification could firm up the grip on the focusser draw tube, if necessary.
That "gunsight" is good. Except, you need to be able to focus simultaneously on the gun sight elements and the distant objects. For Eric juggling several pairs of distance and close glasses - there is little hope! Kids should do fine with their excellent young eyes.
