Re: At some point, I may begin commenting on the G11 DEC axis...
oh right, another thing is that it STILL takes about 15 seconds after a dither move for the axis to "settle down".? ? Whereby "settle down", I mean that guiding is reliable again without any sudden

Re: At some point, I may begin commenting on the G11 DEC axis...
Hello again, I thought that maybe there would be a lot to say, but there isn't.? The G11 DEC axis seems to work well over a fairly wide range of worm meshes.? Maybe because it has low friction even

Thanks for the write up.? I did not know the ring gear sits on only a needle thrust bearing, and effectively a bushing sleeve.? I would have thought it used a bearing for radial constraint, but ok,

Re: New G11G with subpar guiding
I'll definitely look into PEMPro, Brian also mentioned the Oldham coupler misalignment so that's already someting I'm looking to fix. Hopefully that will get this to be good enough but if not, the

Re: GM8 Counterweight Bar Won't Thread In
The thread is probably 1" x 16tpi.? You can confirm by holding one of Losmandy's 3/8" x 16 tpi bolts up to it to check.

Paypal has just futzed around with the fee structure, so it's best to look at the user's agreement. I scanned it and there are a lot of additional things that will generate fees.

Paul, I'm somewhat mystified why you set your TVC value to zero when imaging. And what do you mean calibration in both directions? The purposed of TVC as I understand things is to nullify Dec

Ken, Polishing the male thread is a common trick used in auto garages where the bolt won't quite fit into the hole anymore. Often it the very tip where the damage is and if you can buff that out you

Re: Need advice selling my Losmandy G11 492 Digital Drive
Jeff, The best way to actually get this equipment sold is to split it up. I'm interested in buying the tripod and @PCBorland is interested in the mount. You will end up money ahead to do it this way.

Hi Ken, If you found metal then there was some type of debris or cross threading. Since this part has close tolerance you need to clean out the debris from the mount as well as the threads on the

Re: New G11G with subpar guiding
Vishal, Your 120 and 60 second errors are integral of the 240s worm period so a PEMPro PEC correction curve might do so good to even these out. If the 120s error is very large and the Oldham couplers

Re: polar scope binding - RA thrust bearing thickness stiction and more.
As a second note, I'm finding that the RA axis is a bit stiff. There is plenty of lubrication on the axial needle bearings. Perhaps too much. The lubricant is a whitish material with a tinge of red. I
