Today I came upclose with the #German made #DocterOptic #Telescope. Did you know that #nitrogen field that is sealed inside the #lens of this instrument prevents any form of fungus, haze or bacteria from forming within it? Go figure!

Now, if only someone came up with a economical means to get them into commercial lenses!
