Re: [APML] First attempt at stacking - Barn door shots of Andromeda,Cassiopeia

Oops, forgot to put that piece of information on the
web page.  I have the lens at f/2.8.  I've found
that's the sweet spot for 5-minute barn door shots. 
If I stopped to f/4 on E200, I don't think 5 minutes
would record very much.
