Hi guys. I'm new to this group. I just bought a used Mach1GTO and received the mount yesterday. The mount is beautiful! I fully assembled the mount at home today and I found out that the DEC motor was

Thank you Roland.

Hi guys. I received the mount few days ago and it has been raining here so I haven't been able to go out with the mount. I'm playing around with the mount inside and I'm getting used to the mount. Eve

Thank you Steve. I will look through the documents in Ray's website.

Thank you Larry for the link to the new version of the manual. I will look through the manual.

I just ordered a USB to serial cable and a serial cable. The previous owner somehow didn't send me the serial cable. In the mean time, I like to try the mount controlling with the keypad but autoguidi

Hi guys. I just purchased a used Mach1GTO and I had the first light last night. The session goes relatively smooth but I was noticing constant drift in the RA axis. First I noticed that the PHD always

Thank you. I will dial in the polar alignment first.

Hi guys, I'm an owner of Mach1GTO. I'm very interested in APCC but I don't fully understand what exactly it is. Is APCC an application using the AP ASCOM driver or some sort of driver? I'm using Seque

Hi Tom, Sure no problem. Thank you. Dong Hun

Hi Don, Is 24h position pointing directly toward the RAPAS objective lens direction in your scope? Thank you. Donghun

Ah this is a bad news. I think I need to return the scope to AP for service. I'm not confident that I can adjust that. The unit needs dead on accuracy. It is strange that this happens. I never touched

Thank you guys for the help. I remember I used the Polaris method to align the bubble level for the Takahashi mount polar finder. I'm surprised that the reticle can get out of alignment so easily. It

I think that you are right. Loosen the 'Do Not loosen screw' and rotate the part with the jack for the LED to align. Donghun

Take a look at these comparison photos between G11 and Mach1GTO. You can see Mach1GTO is more substantial mount even tough it is lighter. I doubt that G11 will handle more than Mach1GTO. http://oc-ais

Hi, I started getting this error and when the error happens, the mount is disconnected from my PC. If I unplug and plug the USB again, I can reconnect to the mount from the PC. Here is the capture of

Hi Ray, Where can I find the log? Thank you. Donghun

Ray, I will post the log files when I get home. I use Windows 7 and Mach1GTO. I'm not sure about the control box. Do you mean the chip revision? Thank you. Donghun
