I am using a G11G purchased new in December 2018. Currently I have mounted a C11 with external focuser and imaging train with a cooled ZWO camera, aluminum dew shield on the front. Earlier this year I was using a C8 with the Hyperstar unit. The last few months I have noticed that my tracking in RA is less accurate than last year. Previously I could get 60 second exposures with the C8+Hyperstar, but my maximum this summer was 30 seconds without clearly oval stars. I now have the same issues with the C11 at f/7. The go to function is perfect and I seem to have no issues with Dec drift. Using the HC Mount Balance function, my offset on the RA axis consistently shows a value of negative 6 or so and the PWM ranges to 12-15% while tracking.
i have played with balancing every session, and check polar alignment frequently. Is it possible that I need to make a small mechanical adjustment on my RA worm drive? I am not mechanically inclined so I have avoided doing anything to the factory adjustment. If someone can give me a Dummies Guide to Adjusting Your G11 Without Sending It Back to Scott, I would appreciate it.
