Re: Pier side
Thanks for the reply, Ed

Re: Pier side
I think of it as where the telescope is pointing. So in the northern hemisphere, standing behind the mount, west is pointing left and east is pointing right.
No expert here, but I believe that is the

Hi All
I know this is not a Losmandy specific question but since I'm STILL

Re: RA guiding awful after upgrade

Re: RA guiding awful after upgrade
Can't give you a definitive advice, Tom, since none of us know for sure what's going on. If you can test with an non-over tightened clutch, first, and then, if that doesn't help, try removing the RA

Re: Specs for the main axis thrust bearings.
Tim,
If you are tightening down the clutches because you have slippage, it sounds like you have oily discs as was mentioned. But instead of a wrench you may wish to invest in the Losmandy clutch

Re: Specs for the main axis thrust bearings.
Tim, drive noises during guiding? What does it sound like?
The guiding behavior looks like backlash, possibly a poorly adjusted spring-loaded worm. Do you have any recent PHD2 guide logs? The ones

Re: Specs for the main axis thrust bearings.
The mount does not seem to stop. The guiding will correct itself in 2-3 pulses after the 30 second phase and the mount continues to make drive noises. As far as did the mount receive a guide pulse, I
