I have a Kowa TSN-824M, and I'd like to get something smaller, lighter and angled. I'm looking at the Kowa TSN 663 ED angled, and wondering if the 20-60 zoom eyepiece and the 30X wide angle eyepiece I already have (for the TSN-824M) would fit this scope.
Thanks for your inquiry.
The eyepieces that you have for your 824M will only fit that series of scope. The eyepieces for the 663ED are very similar in design, but the bayonet attachment is not compatible between those two generations of scopes.
If you have any other questions, just give us a call.
