Thanks Terry and Clive.
I will post images of set up,its all in a permanent observatory set up on pier,very sold PA.
The guide scope is on top of the 4 inch refractor,towards the end,Maybe this set up is not suitable,most do 'side by side'
I will hold off pulling all the motors off and opening up the mount to fiddle with worms.I will turn off the Backlash comp as Terry mentions.
Thanks again for your suggestions,Ideally I'd like to take five minute subs and darks and use DSS and get some sort of images on a regular basis,as I have invested a bit building observatory.
Cheers Chris
