In the spring of 2004, Celestron introduced a new NexStar GT model with
a 76mm Newtonian reflector optical tube. The general description of
GT mount as found in The NexStar User's Guide applies equally to this scope.
The NexStar 76 is a small step up from the NexStar 60, but still a
very limited scope. Deep sky objects will be slightly brighter,
but still this scope is mainly limited to planetary and lunar
exploration as well as double stars and open star clusters. To
enjoy views of the planets and Moon that are improved over the NexStar
60, you
will need to master collimation of the scope. While not terribly
difficult, collimation is a daunting task for a newcomer to astronomy -
the most likely person to purchase a scope like this. If you live
