Hi Daniel, my distance from focal reducer to camera is about 90mm. I spoke to the nice people at Bintel who suggested a 2" SCT Adaptor. This has given me a flatter field with less vignetting than previous set-up (it is also much easier to achieve focus). My previous set-up had a distance of 115mm, which gave me all sorts of problems.
