Yep. If you are too close you will get "reverse coma", Which I believe is referred to as Over-correction.

I've got a CFW on my ST8300 that takes up about 22mm, so I had a custom made adapter to suit the MPCC given the distance from the CCD to the front of the CFW, taking into account the width of the filters..

If you're not using a CFW at the moment, a 40mm Male to Female T-thread extension will get you pretty damn close if its screwed straight onto the front of the ST8300, and into the MPCC. It will give you 57mm spacing, which is within spec and should produce good results...

I have a spare one here.. If you want it, its yours.. PM me with your address and I can get it in the post monday...

Cheers mate, and good luck with the new camera!
