  We at Steward Observatory are using Prontor shutter in the 4" and 6"
size.
they work very good but are a little slow ( 60 msec min exposure). they
also
need a good driver for them. We had to build our own as the one the use for
the 4" didn't last very long with the long exposure times we use. The cost
is
about $1000 for the 4" and $2000 for the 6".
  They can be purchased through:

		 Geiss-America
		4821 W. Main St.
		Skokie, ILL 60077
		Ph. (312) 674-5800
