ATM baffles

[JHM.van.Gastel@psy.vu.nl]

In the Astronomy issue of september (or august?) I read the article about 
baffling. Because have have to carry my 12 inch telescope (30 kilogrammes) 
two stairs up to a roof-terrace each time I want to use it, I don't want to 
make it heavier. So I looked for very light material to make the 
baffle-rings. I made them from a kind of foam, used as undergroud for wooden 
(parquet) floors. It is very light, 3 mm thick and stiff enough to stay in 
the right shape. It's easy to cut with a hook-formed stanley-knife. It's also 
paintable. I am going to mount the rings by glueing them on small wooden 
blocks with velcro (to be able to replace them if nessasary). The blocks I 
glue to the tube wall with two-sided self-adhisive tape.

Greetings,
