Focal Reducer: seeing secondary?
Folks - if I fit an f/6.3 SCT reducer/corrector to my C11, I can see the secondary mirror obscuring the FoV unless I get my eye closer to the EP than usual.
This happens with 25 & 40 mm Celestron E-lux and 24 mm TV Panoptic EPs.
Can this be fixed?
Would changing the focal length help (extension tube?)?
I don't want to reduce the FoV by increasing the focal length - otherwise, what's the point of the reducer?!
