Thanks, Dave . . . good point! Michael, you may have hit on the problem. Since the drives work fine in Sidereal mode, and since the Gemini looks fine until the mount needs to actually move, the

Hi Greg, Some actions to try: I think you said your RA has the high precision Ovision worm system. So Chip's comment about the brass Losmandy worm does not apply to that. I don't have an Ovision

Hi Greg, A couple of thoughts on your process. You are not likely to get very low tracking error numbers with the stainless steel worms, you must have brass worms for the best precision and

Forgot to mention G11 is pier mounted

Recently Purchased a used G11 with G1 controller I gave up on using the RS232 interface....it will connect at times others it will not,. Tried 2 different Apdapters USB to 9 pin, Cable is sound,

Happy Thanksgiving, all. Thanks, David, for explaining that the Gemini system only measures changes in motor position, that it does not know its exact position. I am wondering if Bob has some

The G1 and G2 have no idea whether the mount is at the CWD position or where it is actually pointing at any time, as there are no sensors in the mount to tell them that. The encoders on the motors

Thanks Paul, Michael,and Don for the comments and suggestions. Here are a few responses: 1. I'm using only the HC, no PC. 2. Right! EST - 5 hrs 3. This problem started with my original ver 1.01.

Bob, One thing to check is have the mount park in the CWD position to confirm it stops at the correct position. If not, then after parking turn off the mount and move the DEC shaft to the CWD

I have shared the same unwelcome experiences too. My advice is try this. Leave the Gemini1 disconnected from any computer. Why: There is a Gemini.net checkbox that allows the PC to send "default"

Hi Bob, You've done quite a bit of troubleshooting, all the basic things I would've checked. Since the problem appears to be related to your mount settings, this where we should concentrate. 1.

Perhaps someone here has an idea or two that would help me. I have a GM-8 with Gemini 1 that worked flawlessly from when I purchased it in 2006 until 2015 when I had to pack up the mount for a

I also had a cracked gearbox causing a wiggly motor. Scott fixed the gearbox for free. Keith

I had a cracked gearbox that resulted in a loose motor. Be sure to check for that, too.

For an object at the celestial equator, I don’t think cone error will have any first-order impact on guiding. It shouldn’t lead to the drift in declination that Magnus is seeing. This also means

Hi! Isn't cone error something else? That does not "affect" polar alignment, but causes field rotation and similar problems. I mean, polar alignment and drift alignment depends on the mount, not on

Still Have the Gemini 1 for sale? Mine is way flakey Greg
