Hello there, Is there any reason other than a leaking seal that could cause this scope to Fog, The weather was not very cold it was about 8*C when I noticed it Fogged. Thanking you in advance. This scope is less than 12Mths old.

It shouldn't.

Have you used it in bad weather before this occurred? Do you have the 20x60 zoom eyepiece on your scope? This eyepiece should be waterproof on the scope but there are reports of leaking. Have you switched eyepieces when it was raining, or in damp weather? Where is the fogging situated, is it on the objective? Or in the eyepiece?
I have the 65 Diascope with fixed 23x eyepiece, and I've used it in adverse weather conditions quite a few times, but it never fogged up during the 3 years I have it now.

It seems there is a leaking seal on yours, the scope is nitrogen-filled and ought to be water-and fogproof.

Kind regards, Ronald
