Tim in a way it is, the early guys were inventing the telescope, and a number of solutions were tried, although I am unaware of the scope you have decribed,maybe the guy who experimented with it saw the correction it gave too, but the power was too low,And in those days they wanted as much power that could be obtained to see the brand new frontier. Nowdays it does not matter if a scope is dedicated to low power, we are spoilt for choice.
