Dear all,
I have a pair of 20x60 Tento binoculars, which we've had for some years.
Unfortunately, my partner dropped them onto concrete. They now have double images. I'm not knowledgeable about the workings of binoculars, but figure that it won't be worth the cost of getting them professionally fixed.
Is there anything I can try to fix them. I found this page on collumating binoculars http://www.cloudynights.com/item.php?item_id=416 but I don't know how to open up the binoculars to access the prism adjusting screws.
Any advice?
Its best not to open them up yourself - I don't think it costs so much to have them done - someone from the UK will recommend somewhere I'm sure.
If you decide not to go down the professional repair route, and just want the binoculars to be functional (if not completely weatherproof), you could try unscrewing one of the objective lens barrels slightly. When I was a 13 yr old birder with bins from the local Exchange and Mart and no money for repairs (paper rounds didn't pay that well!), I found that slight double-vision could be cured thus! It's only an option prior to chucking the bins though, and a proper repair would be best.
