The EQ6 is difficult to polar align in Altitude, especially when fully loaded, the Knobs Mod can help, but only so far because the design of the altitude adjustment is flawed. Modern Astronomy make a ‘rail mod’ this corrects the design and makes precise polar alignment in altitude really smooth. I won’t go into the installation here, but it is straightforward, the altitude bearing/bolt covers are liekly to be damaged when you remove them (I got mine off ok but this is apparently unusual) so the kit does come with some nice metal new ones (although I prefer the originals).
Concept
Getting the altitude bearing bolt covers off is the hardest part of this mod, you will likely destroy them, fortunately the kit from Modern Astronomy comes with some new ones.
