vingetting with focal reducer?
Posted By Mark Rice
Bill, if you're talking about a reducer and a binoviewer, it shouldn't. My binoviewer works just fine in my SCT with 24mm wide angle ep's and .6(?) reducer. No vignetting that I can see. What didn't work was trying it with my .63 SCT reducer. Wouldn't come close to focus. If you're viewing mono it should work great.
