Re: GPS suggestion that work well with APCC #APCC

I have the StarGPS module for AP CP2/CP3/CP4/CP5 controllers. Works precisely as advertised and Chris Carson is a pleasure to deal with.

All-in-all, I am not sure it is a critical investment unless you are planning a lot of traveling with your AP mount and prefer to initialize the mount with your AP hand controller versus APCC or through Sky Safari or Luminos.

Yes, StarGPS does have specific instructions for AP mounts.  Here’s the link:


I forgot that another suggestion they make is to switch to UTC for your HC.  And I indeed set most of my mounts to 00 offset – or UTC.

It’s been a long time since I’ve used my Mach1.  But as I recall, there’s a setting in the HC that tells it where to look for time/date/location data.  It can be set to look to the HC for that data, or externally – in your computer for example.  You need to set it to look externally for time/date/location data.


I think there are maybe three settings.  The one you want looks externally and waits.  And when it gets the data, puts it in the controller and/or HC.


As I recall, there’s a flashing light on the side of the StarGPS.  It flashes at different rates to let you know what it’s doing.  One rate tells you it’s looking for a fix.  Another rate tells you it’s got a fix.  And as I recall, there’s a third blink or something that tells you it’s successfully passed the data onto your mount.


I believe you’ll find much or all this information on StarGPS’s website.  They have specific instructions for each mount.  And I believe all AP mounts work the same way in this regard.  And some of this might even be in the AP Mach1/2 manual.


Again, I haven’t used my Mach1 in years and just don’t remember.  And I’m up in the mountains in our trailer now and don’t have access to my notebook.

It was easy to find. Thanks. Oh, I’ve already fired off a question to them asking about compatibility with the CP5.  By the way, what does “set your controller properly” mean, exactly?
