Re: [APML] 'challenge'

Hi Stephen,

I think it will be interesting just to find out what techniques work well in a real time 
sense. A variety of experimentation is good....two scopes, one or two image series 
with one scope, or maybe simultaneous RGB series on each quadrant of a CCD since 
M1 and Saturn are so small and then recombining them. 

In any event it should be fun!
