A guy called Mark helped me out with a measuring method on another forum.
How to measure the offset away from the focuser?
I am glad I didn't disassemble my Newt before measuring it.
I used 2 rolled up pieces paper with masking tape around them and kept trimming them until
they would sit by themselves between the secondary and the other side of the tube.
I was expecting to find that the offset was away from the focuser by 5.5 mm
but instead the focuser side was shorter by 1.3 mm.
The offset is wrong in value and it's wrong in direction as set up by TS in Germany.
Now I'm going to have to work out how I will do that offset myself when the spider is reinstalled.
see pic.
cheers
Allan
