Re: Mach1 Unable to Find Home Position Suddenly
The accuracy of your PC clock and, by extension, the clock in the mount control box, is crucial regardless of the situation.toggle quoted messageShow quoted text
I presume you are initializing the mount using the A-P ASCOM driver from your PC (that means if your hand controller is connected to the mount, it is in EXT mode and you do no select the location info to initialize with from it.)
First, ensure that your ASCOM driver has the "sync PC time to mount" option set.
Second, ensure that your PC's clock is accurate. I know it's common to have observatory computers cut off from the network, which means that they cannot avail themselves to the services of NTP servers that any modern OS will automatically try to connect to. If you choose to have your PC cut off in such a way, you will need to sync it from an external source such as a GPS or keep adjusting the time by hand. if your PC is connected to the internet, ensure that Windows is syncing to NTP servers. On Windows 10, that would mean going to Date & Time settings and ensuring that "Set time automatically" is set to On.
If you don't have an accurate time app on your mobile phone, you can quickly call the US Naval Observatory master clock at +1 202-762-1069 for an automated readout and prompting of the current time down to the second. There is a service for Mountain time at +1 719-567-6742.
