what is the make and model of the cam? I know you want to have a long
exposer time and getting a program for it is not easy.

My son wants me to get a cam for his telescope, but cash is not easy right now.
At least we belong to http://www.cedar-astronomers.org/ and can vid the stars
with the big telescopes.
