I have a Baader MPCC MkIII which I've had endless problems getting a back focus to suit my set-up, so I bought the TS 1.0x GPU from FLO. Fitted a Nikon adapter to it, put the body on (800E full frame), and plugged it into the the focuser. It gives you about 20mm extra focus extension so I made a guess at that and a few test exposures to get stars reasonably in focus before running auto focus in Astroart 8. Stars across the field all nice and sharp. I have some vignetting at the corners so not completely filling the full frame format but that is probably more to do with the secondary mirror size on my Newtonian. I'm only intending to use this with a APS-C format astro camera so the Nikon full frame was a bit belt and braces to make sure there were no isses. Highly recommend.
