I recently purchased a Skywatcher EQ6-R Pro mount. Highpointscientific.com ended up replacing the one I bought a few months ago because the counterweight shaft fell out, and now I am having issues with the replacement.
First of all, the RMS error is not good--at least not as good as the original one I had replaced. I had RMS errors around .8" on bad nights with the original EQ6-R, this new one is at LEAST 1.32"on a good night, sometimes going all the way up to 2" total RMS error. I'm using the exact same settings as I did when I had the original mount with the bad counterweight shaft. It starts off decent for the first hour or two, and after a while it just progressively gets worst, no matter where I am pointing. I also know I have bad backlash, and it is not even measurable in PHD2...
Furthermore, for the last week or so, the RA axis gets stuck. It has happened about 4 times or so. EQMod says it is tracking but it is not tracking in the RA axis, and the guiding gets out of control, until the PHD2 star gets lost. I try to park the mount, and it only parks in the DEC axis, while the RA axis gets stuck. I have to restart the mount to get it going again, and when I start back up, the guiding is terrible.
I have already checked the power and the USB cable, I know that is not the issue. I plug it directly from the USB port on the mount, and don't use a hand controller.
I reached out to both skywatcher and Highpoint, but I wanted to see if anyone here has any suggestions... It is pretty frustrating, especially since this is the second skywatcher mount I have had issues with...
I'm using a side-by-side guiding setup, with a ES 80mm FCD100. I have about 12 - 14 lbs. on top of the mount. I am perfectly balanced, and I have been making sure too. Please let me know if there is anymore info I can provide.
