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

Isn't this a text book definition of "Cone Error"?? Not that I know anything about it.. Derek _____ Sent: Saturday, November 18, 2017 1:41 AM To:

hi, I'm not clear on just what may be loose. Here are some ideas to check out: (this is for a conventional G11 or GM8, with or without OPW. One with an Ovision may be different.) The motor is

there is wiggle in the housing, it's normal. I am not a mechanical expert, but i believe the iwggle is in the housing, not in the motor itself or the connections. You will always have that wiggle

Hi! Here I am again with a new question (I am soo happy that my previous "not performing Go To Bright Star" was solved!!!): I'm trying to improve mu guiding (of course). So I'm experimenting a lot

How may I tighten up my dec motor housing? It has an 1/8 inch or so play when I grasp the housing and wiggle. The G-11 is newly acquired so I am reluctant to try to use the drive with the looseness

Hi Jim, I had an 8" EdgeHD, round stars with an EdgeHD OTA are standard equipment. That's certainly going to be a nice setup, a bit long for my favorite subjects without the reducer and a full

Sold a CPC1100 and CGEM to put toward a G-11 and 11" Edge HD. Still hope to gather the same amount of photons, just expect to get rounder stars. Jim

Hi John, The newer Losmandy gearboxes have bronze bushings on the axles so a drop of light machine oil on the visible bushing the best lubricant for this use. As far as a lubricant for the worm

Hi Jim, Oh, tell us what you bought so I can live vicariously! I'm broke now, between the last kid in college and a tax return surprise I did not anticipate my astro spending has to be curtailed

I have found that the bushings tend to dry out.? I usually just open the gearbox and take some the grease from the gears(there should be plenty) and apply to the bushings and gear shafts. Jeff

Hi I have a G11 with Gemini 2, which is about for years old. The drive motors/gearboxes have always made some noise when slewing, but they appear to be coming noisier. A friend suggested that I

Thanks Chip. With luck, I made the correct guesstimate on my counterweight requirements. Now if my back-ordered setup will just get here, I'll enjoy an early Christmas! Jim

Hi Jim, The drawing and calculation method doesn't include the not insignificant weight of the counter weight shaft. so having too much weight is a possibility. I find that if I know the weight of

Bill, I had a 1992 Meade LX200 Standard Field Tripod and attached the to it using 2-3 1/4-20 cap bolts into drilled tapped holes and backed up by the 1/2"-13 threaded spreader rod. I had also done
