@ 1ponders: thanks for the formula, this will certainly come in handy
.
@ g__day: 1.) I'm buying it from an astrophotographer who's pulling the plug on his hobby. So it's second hand. If I would have to give a price to the mount alone I think it'll be 700~800 euros (since I'm getting a lot of extras with it). So it's almost cheaper then a regular EQ-6 here in Europe and that with the Skysensor
. But he's going to show me almost everything I need to know about it + he's going to show me that it still works when I'm going to pick it up.
2.) The Skysensor is the original Goto from Vixen and if I understand it right the Skyscan and other versions of it are copies (sort of). This EQ-6 had the SS2k PC placed by a german company so normally it should work pretty decent. I've looked at some other mount done by the same company and they all show nice PE (somewhere around 12").
