Hello All I am a brand new user of Losmandy mounts. My past experience with GEMs has been limited to the iOptron SGP and the Vixen GPDX. I recently acquired a Celestron Losmandy G11. I tried to

Hi Tom, I did the fan change on the 2600MM and I can't say it ever improved any of my images. But I don't think that would affect guiding on one side of the meridian versus the other. It sounds like

One thing from the comment Derek made, if I grab the CW shaft it will move side to side slightly. *** "slightly" is good.. as in a 1/16th of an inch.. I don't use an ASIAir, but it sounds like

Mark, I appreciate your comments and no, I am not looking for perfect guiding.? What is the saying...The perfect is the enemy of the good.? I did have one thought; could the camera fan, if it is out

A tiny amount of wiggle in each axis is normal. Without any "lash" (aka wiggle, slop, choose your word) in one position (location on the worm) there is risk that the gears will bind on another. The

I contacted Losmandy but they weren't able to provide much help beyond check for dragging cables.? I admit, the photos I sent do show a bit of a cable mess but I am sure that is not the problem.?

That seems unlikely to help in this case. The RA Worm appears to behave well, with low error and low PE on the east side of the mount. It's still a good idea to measure the unguided worm performance,

Tom, It is possible that you have an RA worm gear which is rougher on one side of the threads than the other, which would explain the change in guide performance after a flip. But that should not

Y'all are leaving out the NEW pier extension.. .. You installed BOTH a new RA eXT *and* a 12" pier extension, right?? My suggestion would be to take the fully loaded setup and loosen and retighten

To follow up on my previous post Losmandy is an outstanding company in that the people really do their best to support the Losmandy community.? Losmandy fully, and I mean FULLY supports every mount

No. You use PHD2 to autoguide but turn off corrections.? This will display the guide scope data used for correction which will show you the mount's basic mechanical tracking accuracy. -- Chip Louie

Can that be done in the day? Just let it track? Tom

Tom, just making sure: the mount had no such problems before you installed the RA Extension? Did you test it well prior to the installation? As others have said, the extension should have no effect on

There are many potential issues with used mounts and even more with the now classic Losmandy straight line drivetrain with the 2-piece worm bearing blocks.? There are several places where issues can

Thanks John. I bought the mount used but it had never been opened or set up.? It came from company seven and I was told they test each mount.? The motors are not tucked. I was just outside with it

Hi Tom, The RA extension should not have changed anything, but you might just want to eliminate that as a potential source. If you have the tucked motors, your mount is probably at least 10 years or

I guess I can use my absolutely trouble-free, works perfectly every time, never misses a beat, skywatcher eq6-r pro while I am trying to diagnose the finicky losmandy g11g. So the first thing I'll try

It's a complex hobby.? Losmandy doesn't do nighttime testing so you are more likely to find the issue than they are and think of all the fun we'll be having! . -- Chip Louie Chief Daydreamer

Thanks guys.? Do you think I would just be ahead to send the mount into Losmandy and let them figure it out?? I could have them do the tucked in motors at the same time.? I'm not sure I am
