Stan, I'm not sure if I would use the gasket material.  Being a paper 
product, it might
very well compress over time giving a sloppy fit.  You might see if you can 
find
a suitable urethane product.  Urethane is made in several properties, one of 
which
is very rubber-like.  The benefit is that it doesn't deteriorate like 
rubber.  As an
example of it's longevity, urethane bushings are used in many automotive 
situations.
Conditions considerably more extreme than a telescope.
