Ok. Let's see what might be wrong: 1. Are your tripod legs really secure? Depending on your tripod, if it has telescoping legs, under heavy weight (depending on your scope and counterweight load), the

Will give this a try. I inspected the mount. Tightened everything and checked the bolts. Mount appears perfect abs rigid and working exactly as it is supposed to. My theory is that my initial

Alan, Are saying that a piece coupler might be best overall in minimizing co-linear problem of the two shafts and provide an overall lower ?240s error? Do you have any recommendations? Peter

I have a quite old G11 (18yrs) with a brass RA and steel DEC worm which I got for $100 w/o weights or controller. With a complete clean/lube and Gemini-II w/new motors- I've used it for about a year

Hi I'm not sure if it will help but i wanted to share my observations from last night which might help fix the issue for you too. First my setup: G811G with Gemini-2 - East Limit (ESL): 99.0 - West

Here are the Pempro files

Edward - have you used the new Smart meridian Flip yet?? How do you like it? ------------------------ Jim W Phoenix, AZ. USA Losmandy GM811G, NINA 1.11, ASI2600MC Pro, Sky-Watcher Scopes

Peter, I would also suggest setting up some dummy targets during the day to watch a number of MF while not trying to sleep. What is NINA actually doing when you expected the flip? For example, if in

What version of NINA are you using, what are all of your settings? Mine are fully described earlier in thread. -- Edward

The set screw is supposed to dig into the shaft of whatever it screws into.? If you like, you can file or mill a small flat for it.? It is the bearing that sets the concentricity of the worm, not

David, You may want to post your PemPro file for analysis help. Go to Documents > CCDWare > PEMProV3 > file.ppc. Your screen shots are not looking healthy. Regards, John

Eric, Isolating the cause of these errors is a difficult process I think. Really I need to test different adjustments, configurations, etc during daylight hours. ?I do have a 0.0001" dial indicator,

Here is the results I got with PEMPro.? I really like this program!? Not as overwhelming as I thought. Will have to buy it if I keep the mount. 7 worm Cycles but the results are all over the place.

Peter, I believe the 76 and 80 second PE components are caused by different mechanisms. The 76 second component is the bearing BPFO (that period can be calculated from the bearing specifications),

My NINA flip failed again last night. Could someone please post their settings that are currently working for them. I'm totally desperate? I need my sleep. Please show image of both NINA and Gemini

With a little digging one quickly realizes that problems with the design of Losmandy's worm block goes back 15 years or more. Their solution is the OPW and more recently to spring load it. I feel they

A bit of a long shot, but it could be that your alt lock bolts are too tight.? If there is a lot of tension between the alt adjustment screw and lock bolts, they might stutter/slip slightly when the

Making a new thread here since this is a bit different than the other one - not sure of the etiquette. After Brian's awesome help, I got setup much better last night with the tripod leg facing north.

Ahhh thankyou Peter I'd doubt the slight divisor "point error" would cause it to lag that much Cheers -- Brendan

Ray, Any thoughts what it could be? Peter
