Awesome! Thank you Geert Donghun

Hi I tried to order an item from AP website and I cannot choose any other country than US as the destination country for shipping. Is AP currently shipping only to US? Thank you Donghun

Hi guys I'm currently using three 9lb counterweights and they are currently haning closes to the end of the 1.125" shaft on my Mach1GTO. To reduce moemtum arm, I'm thinkg of adding another counterweig

Thank you guys. I will get a new USB/Serial cable first. The trouble is that this doesn't happen all the time but only happens once in a while so it is difficult to find out what the faulty part is. D

Hi Ray, I've been using this USB/serial driver without a problem about two years. Is it more likely USB/serial cable problem or the serial cable itself? Thank you very much. Donghun

Hi Ray, Here is the log archive. AP AP Shared with Dropbox View on www.dropbox.com Preview by Yahoo I'm seeing these warnings in the log. 000043 2014-06-05 23:43:54.189: Telescope: Warning : Retransmi

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

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

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

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

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

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

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

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

Hi guys, Last night I looked through RAPAS first time in a while and I realized 24h position is not pointing straight up (not straight toward the RAPAS objective direction). I'm pretty sure my memory

I have similar experience as Jon seeing drift in RA when unguided. Can APCC correct this? Thank you. Donghun

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

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

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

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
