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

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

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

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

Hi Brian, Thanks for your response. Yes the fine copper wavy is there under the lock collar to keep some spring pressure against the polar scope. the collar and setscrew were loose when I bought the

that's pretty typical. there are ways to effectively balance it, we did a video on this https://www.youtube.com/watch?v=qHJYkJLBZDc Regarding the grease, we use arctic lube, and many others like

Michael and make sure I can still rotate the scope but that there's no play. Can you check and make sure the copper-colored wavy ring in the polar scope's locking collar? wrote:

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

Hello, I just bought a G11 and am working through it's issues. I know every mount has it's quirks, but some of these I didn't expect. RA axis the polar scope locking collar was very loose. So I snug

Ken, You may want to carefully inspect the threads on the bar, especially towards the end. Make sure there are no nicks or flat spots on the high points on the threads and that they taper into

Thank you for the modified driver.? I will test it out.

I always leave TVC set at 0 when imaging. When I need to calibrate the auto-guider, I set the TVC value that results in about equal calibration in both directions. Then I turn off TVC for the rest of

It makes sense that these parts fit correctly when the mount was made. So it's most likely some grit has lodeged in the threads. So first try cleaning and relive...I'll guess that will solve your

Alan, I have no control over the north step size. 500ms sees to be the smallest you can go. Are you referring to something else? Regarding TVC value, I think yo are right. I knocked it down from 90 to

All the north bumps are too big
