Hi,
Just a slight tangent... below is a link that those thinking about upgrading their HEQ5 or EQ6 scopes might find interesting.
I upgraded my HEQ5 about 2 years ago with an upgrade kit from the link below. I also changed the grease and replaced the original drive gearboxes with the more accurate Conrad gearboxes. It has added an amazing amount of functionality to my scope at a very reasonable price.
Regarding some of the questions asked below, it might also be worth looking in the forums at the link below, there is a wealth of knowledge regarding all facits of the upgrade (grease etc).
