Well it is finally finished. Many thanks go to Paul aka Rumples Riot for his input and assistance, would have been up the creek without him. It isnt going to move, 22 bags of premix concrete plus 2 more of cement for added strength has made it a rather solid base. My JMI motorised focuser attachment for the Tak arrives next week so I wont have to touch a thing now other than to change eyepieces etc. Once again thanks very much Paul.
