Thanks Marc – it was a fun and rewarding session, experimenting with the lens.

Quick question. Do you piggy back the camera then have the lens fitted on it or is the lens mounted and the camera hanging of it? I'm asking coz I have bought an adaptor for my CCD to fit on Pentax lenses and I'm not sure about which way I should go.

Hi Marc

I had the 400mm lens fitted in a couple of WO Guiding Rings. The x3 screws in the rings nearest the camera were positioned in the recess where the Canon Tripod Mount Ring A(W) normally fits.

The rings were directly bolted onto a Scopestuff mounting plate and auto guided using a WO66mm Petzval and Orion Deep Space Star Shooter (original model) using PHD Guiding.

Cheers
