I saw a pair of 10x50 Japanese binoculars for £4GBP in a charity shop the other day and felt compelled to rescue them. It wasn’t until I got home that I realised why. Only one side worked, so I’d paid £4 for a monocular. Then I saw in The Times that it’s the Transit of Mercury tomorrow from about 11.45UTC until dark in the UK, so maybe there was hope for getting my £4 worth yet. If I can ever get it focussed and still, and the Sun shines, what are the chances of seeing the transit on our spare bedroom wall using the set up in the photo?
Two more questions:
1. Why does the image on the wall come out at such a funny angle from the eye piece?
2. Why do I have to tilt the binoculars up when I want the image to go down and left when I want it to go right? DaveP
