Fine adjustment Alt/Az plate
Hi Guys - I thought I would show you some pictures of my new alt/az plate. I wasn't happy with the coarsness of the mount's adjustments. They are far from bad but with TPoint and Automapper I can find out polar alignment errors in seconds of arc. I realized I could never make the adjustments even when I knew how much I had to move the scope.
This is the answer and it works very well. I can now make adjustments down to a few arc seconds. The plate is 25mm aluminium. The thread on the altitude bolt is M20x0.5 which of course was custom made. It gives me 6 arc mins per revolution.
It is not light but I think it is a worthwhile additon to my kit.
