Large scope with reducer vs Native
Hi guys,
Theoretical question:
Ignoring the reduction in image circle size (as right now thats the only difference i can see), would the final image be more or less the same & captured in the same time if you had a large but slow scope combined with a reducer so that after the reduction it matched a small but fast scope's focal length & f ratio.
eg.
Scope 1 is 150mm f/8.25, with 0.66 reducer (ends up at 100mm f/5.5)
Scope 2 is 100mm f/5.5 native scope
Would the image circle difference be the only real difference here?
