I just upgraded the chip in the GTOCP3 from "J" version to "V2". Instructions say that I must reinitialize either via the hand controller or computer connection. How do I tell what version of firmware

Thanks for the info. After some light reading I agree with Robert that the clutch plugs are likely the issue with the stiffness. I'm going to take it out tonight and put it thru it's paces to see if t

I was able to pick it up for a couple days of evaluation. I adjusted the backlash on the two axis and took a look at the overall state of the mount. The Dec and RA are stiff with the knobs loose so no

I was on the list for the Mach1 about a month ago. Guess I will just see how it goes with you guys and the list. Certainly is easier to hold onto my money a bit longer. George C. Lutch
