Quote:Luigi - I would not be overly suprised to see a company combine just what you are saying into a telescope. Just turn the unit on and the mount calibrates itself. Of course I think to work the mount and telescope would have to be one single unit like an ETX. Always nice to speculate....I am still mind-boggled over my CGEM All-Star alignment.
The integral camera is what is used for final alignment.
What the original poster asked was if it can be done with GPS, and I said it can't. Cameras, compasses, and levels are not GPS. Perhaps a technical point, but it shouldn't be beyond the ken of most forum members.
the fact is, it could be done without GPS, cameras, or compasses. All that's needed is a camera and software. Think about it, anybody who knows the sky or is reasonably familiar with a planisphere can look at the night sky and figure where things are without needing to know where they are or the time(GPS), the direction (compass), or which way is up (level).
Quote:encoders will be obsolete and GPS will allow you to simply attach a transmitter/receiver to your scope tube to find your way around the night sky?Just a thought...Clear Skies and Peace Out!Bob

Quote:Nope, still used them dadgummed encoders. GPS gives it initial position and time info.

The things we use are receivers. Yes, two receivers place a distance apart could be used to determine direction, and that is an interesting proposition. I don't know how long the baseline would be to get the required accuracy using differential GPS. In this case the two recievers could be linked by wire, or linked by RF, in which case one is a transmitting, tho not GPS signals in the normal sense. Investigating what's being done with DGPS in surveying might provide the answer. Not cheap yet, but it could be in the future. BTW, the software for these devices isn't a walk in the park either.If you could put one receiver on each end of the OTA, encoders wouldn't be necessary. Otherwise, they'd be necessary to keep track of where the OTA is pointing WRT to some arbitrary reference.
