Having now sold my Meade SCT, I no longer require these focal reducers. They are suitable for any F10 SCT as far as I know.
The F6.3 has a scratch in the lens approximately 5mm from the outer edge. I have included an image below taken with this FR & as far as I can tell the scratch does not cause any reflections or other aberrations for imaging or visual work. This FR is suitable for DSLR, dedicated astro camera or visual use with a back spacing of 105mm required to achieve F6.3.
However, noting that it is not blemish free, I have I believe priced it accordingly.... if you believe I am asking too much for this one, please contact me privately to discuss.

The F3.3 is pristine with no blemishes anywhere. This FR is suitable for a dedicated astro camera or visual use requiring a back spacing of 35mm to achieve F3.3. It will not come to focus with a DSLR due to insufficient in travel on the focuser.
