No probs Steve,
Here is the guts of it.
Basically a Phillips Toucam, my lens adaptor and pick a lens for the job.
And
here it is mounted on a tempry fitup until I make an alingable mount for it.
The problem I was having was sorted by increasing the calibration step size to around 2000 and this varies a bit depnding on what lens is fitted to the unit.
The more accuracy I need the longer lens I fit as it will accept all the SLR lenses I have from wide to tele but I've found the 135 works pretty good. If I need a few more stars in the field I just fit a wider lens.
I do still have issues finding a guide star in very low light areas of sky like when working on the LMC.
Still have to do something about that but not sure what as yet.
