Mark,
Resolving power refers to the theoretic smallest angle between two stars that a telescope can separate. The formula is
R = 125/D arcsecond
D is in mms. Therefore a 100mm scope would have a resolving power of 1.25 arc seconds. A 145mm scope would have a resolving power of .86 arc seconds, therefore could "resolve" the separation between closer stars than the 100mm scope. This means the 145mm scope is capable of seeing finer details than the 100mm scope.
Hope this helps.
Randy
