You state the eyepice is not waterproof, are you sure, I have seen many sites say that it is? Afterall what is the point of having a waterproof scope and not the eyepiece?

Until about two weeks ago, we ASSUMED that they were waterproof, but we had one returned full of water, sent it back to the suppliers who informed us that the only waterproof eyepieces for the Kowa scopes are for the new TSN770/880 series scopes.

Looking at the Kowa leaflets, it goes to pains to say how waterproof the scope bodies are, but at the bottom of the page where it lists the eyepiece details, no mention of waterproofing is made.

Is this a wide angle zoom lense, or does kowa not do a wide angle zoom for the TSN-2.

This is the only zoom eyepice Kowa are currently manufacturing that will fit the TSN2.

Considering it is a zoom eyepiece, the angle is quite good.

The TSN1/2/3/4 scopes used the same eyepiece mount as the new TSN661/2/3/4 scopes, indeed many people have bought the new eyepieces for the older scopes and use them very successfully.

The SLR camera adaptor fits in place of the eyepiece (i.e. the eyepiece is removed and the camera adapter used instead)

I would assume that the SLR camera adapter for these scopes should fit the older 77mm scopes, however, I have not tried it (or know anyone who has).

Details of camera adaptors can be found on the Official Kowa Website
