re: Solar Filter (link)

A friend bought a Celestron and a glass filter than went with it, at a Celestron dealer.
I don't know how much he paid for it.
Mine was simply an A4 format filter that cost 1.20 $ or so.
It does produce a blueish sun.
A H Alpha filter! Well, I think I'll wait till I meet someone who's got one.
It did happen in France.
