Hi all

After recently acquiring a William Optics ZenithStar 66 Petzval Semi-APO I've had good views though the GSO 2" SCT 99% dielectric star diagonal and my 1.25" EP's with the adapter. It's absolutely tack-sharp and focuses at around half focuser travel. The image is fantastic for the scope's size.

Last night I tried to fire up my ToUcam at prime focus and simply could not get a focused image at all - no matter what I tried. I tried mounting it with the 1.25" SCT-1.25" screw-on adapter that came with the scope - no go. I tried extending the light path by using a 2" extension tube off the top of the star diagonal - still no go.

Could someone who has one of these please let me know what arrangement they use to get a ToUcam or LPI to focus in one of these refractors?

Cheers
Chris
