Robin I think we have got across I have made a unit to hold the SA200 and my Lodestar CCD so it is just a mater of putting it in the ZS80IIED and all is the same every time all I need to do is focus, from the Grating to CCD Calculator I get 17mm to 30mm I have it set at 23.5mm so the CCD needs to be nearer the SA200, to get image all on screen I have to tern it 45 degrees.
