Hi Alex

Here is my auto guiding configuration using the original Orion Deep Sky Star Shooter on the WO 66 Petzval that I purchased from Ron at Sirius Optics.

You need to be careful with these WO 66 Petzval’s – they require a 2” SCT fit diagonal for visual use although as you can see from the attached file, for auto guiding with the Orion DSSS, I use a WO 1 Ľ inch mirror diagonal and the focuser is racked out at around 3 cms, in its total of 6 cms travel.

My 2” WO Mirror Diagonal has a dual interface eyepiece adapter that I can swap out, from an SCT screw fit to a 2” push fit.
