Popped the mirror in and checked balance and its surprisingly good with
the weight on the laser collimator enough to balance it , this would correspond to a large eyepiece .
Collimation was very easy with the barlowed laser and the catseye centre spot really lights up with the laser .
Have run into an issue which I hope to sort out soon in that when using the pole closest to the focuser to move in Alt the clamp slowly twists changing collimation , it seems to do it quite easily .
It maybe something I have or haven't done but hoping to find a solution soon.
With a bit of luck I may drag it outside and see if it all comes to focus , fingers crossed
