Hi all,

Since upgrading to the SBIG ST8-XME my field has shown quite bad disortions, distortions that were previously just outside the FOV of my ST7, using the standard Meade f/6.3 reducer. I have tried the reducer in many configurations including inset inside the focuser draw tube.

Can anyone recommend a specific focal reducer for the 12" classic which will produce a distortion free (or very close to it) FOV?

Thanks,
Roger.
