I should have added that our Oberwerk/Strathspey have 1.25 inch interchangeable eyepieces.

Go to the Binocular MiniReviews and follow the link to the thread on Eyepieces for the BT100. Post any questions on interchangable eyepieces to that thread which at this point probably includes discussions on about 12-15 different eyepieces for this binocular.

< Unfortunately, despite being built like a tank, ours got knocked out of colimation in transit, so have gone back to be reset. For anyone who has not come across these bins, they come in an intimidatingly large and heavy box! It is difficult to think of such a heavy object being 'fragile', but our seller reckons about 1 in 20 suffer this problem.>
Graham ,
A belated welcome to Cloudy Nights !
With regard to your statement which I've cut and pasted above , are you SURE these 1 in 20 specimens are properly collimated BEFORE they leave the factory ?
To me , 5% sounds like an unlikely high figure for such robust bits of kit to be damaged in the way your supplier is trying to make you believe.
Regards , Kenny

I agree Kenny. In fact, I commented on this post, but I posted the comment in another thread where the discussion was about all binoculars losing collimation in shipping, which I also consider rubbish.
This binocular has one of the most robust prism shelf adjustments you are likely to come across. This binocular would have had to incure some serious abuse, not standard shipping/handling, in order to be knocked out of collimtion during shipping. Either it was out before it was shipped or somebody is literally throwing boxes around.

Thanks for the various greetings and comments. On the robustness of these binoculars I can only repeat what our dealer said, which is that they were checked for collimation before shipping to us! Compared with their trip from China to the UK they did not have to travel far from him to us. When they return we will see if they survive this time.
I am still finding my way around here, so am off to the minireviews to see what more I can learn about eyepieces. Many thanks edz.
