Allen, Brilliant tip!

Sounds like mine. Maybe a half octave higher pitch but same decibel level.

I had the same doubts as Alan when i first got my G811G last month. I compared the noise with my OnStep GM8 which is completely silent and was worried I had installed the motors wrong. Brian told me

My 2005 vintage G11 has caged needle bearings supporting the RA and DEC axles. I have rebuilt several G11 mounts for friends and club members and some may have been newer than mine but almost all had

*The two transfer gears appear to have a dark grey lube on them.* The grease does darken over time, even if using clear Superlube. Metal fines and aluminum oxide from the gears starts to taint the

Related question, which I hope isn't too far off this topic: Has anyone who's adjusted the motors to reduce noise also measured before-and-after PE FFT charts? I am curious whether the mechanical

Hi Alan, There is a simple mechanical procedure to assure accurate CWD: Tools: a short "torpedo level". Procedure: Put your counterweight bar horizontal. Level the counterweight bar with the torpedo

I'm curious what results you are getting with the Sharpcap PA process? Precise CWD hasn't been required in any of the mounts or techniques i've used for polar alignment including Sharpcap I've found

Peter, The backlash on my original Losmandy gearbox is 800 msec. With the gearbox installed on the motor and half the coupling on the output shaft, I took two pictures of the coupling on the output

Where did u clip the laser, and was the worm "loaded normally"? We'll have to see the PHD backlash graphs to figure out what is going on. Dirty little secret : Start the guiding assistant, then click

Alen, first what a great great piece you wrote on backlash. From the graphs you posted I might be too tight? Second, you mentioned going to I think guiding rate and counting. You say you counted 2a

Hi everyone, Simple question I need to ask the group. I ordered GM811 in June, and it will be my first Losmandy mount. In the order I had added the CKS knob upgrade. I did not know if I should have

Other than doing the initial rough alignment on the pole, why would the accurate CWD position matter? If you follow up with any other type of polar alignment routine, the accuracy of the initial

/g/Losmandy_users/message/71205 You can use the laser pointer trick to tell whether the backlash is in the gearing, or the worm to ring gear junction.? Try to have the worm adjusted

Alan, First, I never power through motor stalls. In fact,I do not even get them. ?Second, no, can you post a link please. I like the idea a checking the current and will no that. When you are over

Alen, As someone who has taken apart their worm/motor assembly dozens of times these past few weeks. I have found that a noisy motor is not a good thing. I worry about what is going on inside the

Why don't you level the tripod first?? My HD tripod has two levels on it, which makes it easy.? Then you use the levels on the mount to get it in the home position and adjust AZ with a viewfinder or

Let's assume I think the mount is in CWD position, but the DEC axis is actually 3 degrees off. When I start the polar alignment, I adjust the az knob so the pole is somewhat centered.? To make the
