On the order of the size of jupiter is more the value these systems 
try for.  On the 100" telescope at MWO,we are look for a corrected 
region of about 20-30 arcseconds.  Of course our science images are 
at f/81 making this instrument ideal for objects that are a little 
further away than jupiter, considerably smaller and less bright.
