 My calculations came out .07 X .1 larger than those above... but within the 
realm given the variable projection distances possible with the movable mirror 
of a SCT. My machine hiccupped a while back, and Covington's little applet was 
gone when I restarted... haven't downloaded it again. Did it the old fashioned 
way... pocket calculator.
