RE: [APML] 'challenge'

["Brian Lula" <brianl@polytecpi.com>]

Hi Chris,

I agree with you Chris. The real "challenge" is how to optimize this event real time 
using innovative imaging techniques. It may not look as nice but that's not the point. It 
also makes for a level playing field with Saturn's brightness coming in to play.
