Vixen FL102S
To the above comments:

I did a star test and it did not appear out of collimation. It just did not seem to be able to keep up with the larger aperture scopes. Maybe it had nothing to do with the lack of quality in the refractor. Perhaps it was simply a case where the other two scopes we just fine examples of their designs. This coupled with their intrinsic ability to resolve more detail, because of their larger apertures, resulted in very fine views the refractor could not duplicate. For example, I'm sure the 10" AP Maksutov would have no trouble dispensing with the refractor because it's really about the quality of the optics more than it is about the design. Whatever it was, the refractor just didn't measure up. Perhaps it would be worth having another go with it as I have access to both scopes.

As an aside, I recently picked up an FC76 and love its performance. Very sharp and takes unbelievable amounts of magnification. Viewed Mars at 240X with little image breakdown - very nice.
