Too tight gear mesh can cause motor stall. Peter

Do you have a UPS backing that Powerwex? Brownouts do occur. Idk. If the occasional motor stall doesn't affect your imaging sessions, then you probably could ignore it. If it does affect imaging,

Hi Linwood, A motor stall is reported from the firmware and is not something the software could be doing. When a motor stall occurs, it's like it sounds - the motor stops tracking (it's not the

I was imaging and it was going great, guiding in the 0.18 to 0.25 or so range, all was well and I glanced at the screen and saw stars streaking. APCC was showing tracking=0. I reached over and

Hi Peter, For now, you should keep the A-P hand controller disconnected from the mount and let APCC initialize and park the mount. Park the mount to Park 3 using APCC and manually move the mount if

Hi Brian, It looked like there was a plate solve/sync near the celestial pole. That's a bad area of the sky to do a plate solve because RA can be very inaccurate. Could this be the problem? -Ray

My 1200 still parks one hour CW up after a session started from Park 5. I checked the site time settings, which are correct. I also copied the mount location and time to the hand controller (selection

Hi folks - and probably Ray specifically ;) my plate solve/recals have gone awry - Any suggestions on how to debug are welcome everything's worked great until a few nights ago now plate solves result

Thank you for telling me about the update which I was not aware off. Clear skies! Phil

That is correct, it was revised to 65lbs and that is reflected in the product information/history as well.

I thought I read the capacity was “revised” to 65lb.

Hi Steven,I I am a Mach 1 GTO owner and I am under the impression the Mach 1 GTO max payload is 45 lbs without counterweights. Best, Phillip

Looking at getting a new OTA and want to maximize the upgrade (have a 9.25 SCT now) without replacing the mount. I am wondering about a 12” truss RC (55#) that would put the entire payload weight

I found this: <https://www.astro-physics.com/1612fp> It says it works with the 1600 and all 1200 mounts. --- Mike

Thanks, Mike, that’s all very encouraging. But I had a look at the AP website and could not find a mount adapter for the 1600, although there was one for the 900. Could you have a look at the AP

I decided to tighten up the axis bolts, as Stacey did above. I found that each of the two bolts on the RA axis were loose. In case anyone else is thinking of checking, here is a quick overview of the

Yes; my 12" pier is almost the same -- but only 28" in the ground, with a "club foot" base about 16" in diameter. I reduced the pier diameter to 10" near the top, but didn't need to do that. Should
