Mark - do you have any photos you can post taken through your LX200R?

David the ACF field is not flat, there is still some curvature present. I only have roughies at the moment as I have been otherwise occupied. I have made simple tests to make sure the chip is fully illuminated and the reduction is about right. If you want to see some excellent pics using the Meade ACF/AP CCDT67 combo go to Basnut's website. He has taken some crackers using this combo and a ST10.

Peter the optec 0.7 reducer would be great with a SXVH9, small chips will work, it's just the larger versions that cause trouble.

The meade reducers do not work on the ACF, I have tried..... I would imagine the meade reducers would no longer serve the SCT crowd either as the imaging circle is way too small for modern cameras (e.g. 9mm for the F3.3). Best thing you can do is measure your chip and go hunting for something that will do the job. The fully illuminated circle is important and if it's not stated steer clear. These are just my thoughts after wasting a heap of money.
