Hi all,
I was trying this device tonight for the first time. Had the 40D camera focused and 40mm Kellner eyepiece in the off axis/flip mirror turret. Centred on "The Box" planetary nebula. Moved the prism out of the centre of the FOV and found a bright guide star. Put the Orion Starshoot auto guider where the 40mm eyepiece was, But could not get focus. Had to move the auto guider further in, like about 50mm. Tried a barlow lens, but that didn't help to bring out the focus point further.
So I think I need a spacer to put between the rear of the off axis/flip mirror and camera. Think I will need a 25mm and a 50mm spacer, better to have too much than not enough, as I can always pull the guider out slightly.
Any suggestions. I have sent a email back to Germany, to see what they suggest.
