Agreed.. I can resolve it under ideal cirumstances in an FS78, Brandon
80APO, 90mm Vixen fluorite. But at high power. Superbly resolved in an A/P
Traveler and FC100 at 100x. At low power inthose scopes, however, there is
just a hint of resolution. 16x80s will give as much effective light
throughput as those 4" scopes.
