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

Thank for the reply Michael. Good tip to use a bottle brush to clean out the threads. And I've seen others mention using a strap wrench, so I'll look to get one. I guess I'm not sure if I should force

You used too much TVC and the overcorrection shows in the guide logs.

Hi Ken, The threads on my counterweight shafts are tight also. I don't know what the spec is or even if there is a soec on the thread suze. Probably matched up at the dmfsctory when new. It's hard to

Hi All,? ?I'm a new GM8 owner, and new to trying astroimaging.? I ran into a problem that I can't seem to figure out.? A couple of nights ago, when tearing down at the end of the session, the

I was able to run the baseline sequence last night, in the attached guide log this is the 55m section. This was on a fresh install of phd and using a new profile created using the new profile wizard.

Allan, I measured the backlash with TVC = 0 and PHD2 returned a value of just under 2s. With TVC = 85 (0.14 arc-sec step resolution) , or 21 at 0.57 arc-sec step resolution,? the backlash measured in

Hi Bill, The WO 50mm is what I used for awhile before I moved to a larger guide scope. I had to insert one 1.25" eyepiece extension to gain proper backfocus. Even with the threads full out there was

I know what the real backlash is, I already said, I put it at 2s. It's about guiding performance surely:) Now, I just rebuilt the Dec access using the 1024 encoder and the 25:1 gearbox. I can confirm

So my first try at calibrating didn't go so well, but it wasn't a mount issue.? I couldn't for the life of me get a good focus with the guide setup that was good enough for guide assistant to be
