Optical Glass Types Explained

Man I want the 127XL so bad. They look cooler than any telescope

Well, I might be a little biased- but I completely agree.

Do you have sales representative in any EU country?

[@oberwerkoptics]

Yes, oberwerk.eu is based in Italy.

I'm interested in both the 120XL and 127XL. Besides having slightly larger objectives, is the optical quality of the 127 better than the 120 ? The 127 offers about 12% more light gathering ability over the 120. I wonder if it's worth the extra $1600. Thanks in advance.

Thank you for the information, Kevin. What is the best method to clean the eyepieces and objective glass? This subject matter may make another great video!

[@oberwerkoptics]

We recommend the LensPen, which is a dry cleaning method that unlike liquid cleaning methods, won't leave streaks behind.

So many different glasses I am confused Canon stated their glass is UD (Ultra low dispersion) in their image stabilization binoculars,many others rate SD as only standard definition, lower quality than ed and much lower quality than UD,no wonder everyone is confused,SD,ED,UD i'm even more confused

Eliminate the background music, very distracting.
