I have a C11 SCT, which I understand is an F10. This is an example of a photo at prime focus with a Canon 400d.
I also understand a focal reducer will change this to an F6.3? What will this do to my images?
Is that right?
Can anyone post me a comparison photo? Im trying to wrap my head around this, "F" stuff.
Also, I'm thinking of mounting an ED80 to the top. How will the image compare to the C11 at F10 of F6.3?
