[Omaroo (Chris Malikoff)]

I'll take a leap of faith here and assume that the C9.25 is going to behave the same way my C8 does with a Meade FR attached.

I had great difficulty getting my 350D to come to focus with the f/6.3 FR attached unless I shortened the image train significantly from the Meade tube's 110-odd mm. The Meade adapter was still too long, and the one that Bintel sells which can be separated into a shorter length is very hard to find. Bintel is out and has been for a while.

I discovered that even better than the Meade t-adapter tube was Bintels' SCT diagonal's screw-on tube (removed). It creates a total length of 76mm between the rear element of the FR to the sensor plane within the 350D and reaches focus perfectly - even for visual.

If you contact Michael Chaytor at Bintel he'll know what I mean if you mention it to him. I showed him my fix using this section of tube and he showed be a box of these tubes that he had on his shelf which were "I don't know what to do with these" spares. They work very well and he'll sell you one at a nominal price. He agreed that the Meade tube did not work for me and was too long. Maybe the 9.25 is different, but I don't think so.

Here's mine. Good luck!
