The polar scope arrived complete with instructions in Japanese.
Thankfully the booklet that came with the Polarie has the instructions in English.
It's a fairly large thing with respect to the unit itself, not sure why but I was expecting something a bit smaller.
Without having a chance to test it yet the only thing that springs to mind is it will add an extra variable into the initial setup and I imagine great care will be needed once aligned not to knock everything out of alignment when removing the PS and connecting the camera to it.
I guess just take it easy and carefully and it will become easier with practice, I'll do a trial set up of it today to see if this part is fiddly or not.
