Re: [APML] stacking & adding film images

Steve,

One more thing to consider is the possibility that exposing E200 beyond 1 
hour makes very little difference due to the film's reciprocity failure.  
At some point, the film just can't record any more "photons"; hence, it
may never make it to a very dark skies' limiting magnitude before
quiting; whereas, a CCD easily can achieve this given enough exposure
and/or stacking.
