Hi,
also be aware that there are several versions of the Sharpstar 61.
Some are FPL51 triplets and others are FPL53 triplets which are more expensive. Testar has the FPL53 versions:

The Raptor does not specify glass, so it is most likely based on the FPL51 cheaper/ earlier version.....
just sayin' be careful about comparing scopes and read the fine print specs....
