5.0 out of 5 stars Celestron GPS, July 19, 2006

A must-have for your older Celestron scope. It takes all the hassle out of alignment and I find that I observe much more often than before. Unlike an EQ mount, these scopes can take some time to align to north and 2 reference stars. No more guessing or looking up longitude, latitude and exact time. Setup at any dark site now takes less than 2 minutes! Works flawlessly and seamlessly with CdS and ASCOM plugins for computer control and imaging. If you have an older scope without GPS, you gotta have this.

3.0 out of 5 stars Useful, but not as much as expected, January 20, 2008

This unit has a GPS unit, an electronic compass, and an electronic level built in. Your scope will only use the GPS part, and it will only use it to set your location, and the time. Since the scope remembers the last location you entered, and has an internal clock to keep track of time, after you first set it, this doesn't supply anything absolutley necessary if you always use your telescope in the same place. On the other hand, if you take you scope with you to various places not near your home location, it can be very useful, especially if you change time zones.

I bought the GPS attachment to the telescope and was quite disappointed with it. It failed to work properly so I returned it. It did not establish my location, was slow to operate, etc.
