Jack,
It is the small one pictured in my last posting. I will get round it,just means I’ll have to modify the bracket on the motor.If I cannot get it to fit satisfactorily then I’ll attach it to my 6″ refractor and keep the Skywatcher on the Lhires
Only being bulky other than that it works I have no problem with it at all. In fact if the box covering the motor were to be reduced to just cover the cog and slot to stop light and dust then I believe most of the bulk will be lost. The motor works with the HitechAstro focus controller for PC control. I recommend it for the job 🙂
Best Regards
Alun
