In the spring of 2004, Celestron introduced a new NexStar GT model
employing
a 102mm short-tube refractor. The general description of
GT mount as found in The NexStar User's Guide applies equally to this scope.
The NexStar 102 is the big brother to the NexStar 80. Like the
NexStar 80, this scope is a short-tube achromatic refractor. The
focuser is a 2" variety and the scope comes with 2" to 1.25" adapter and
1.25" diagonal. The extremely wide field of view and added
light-gathering ability make this an excellent scope for exciting views of
open clusters, nebulae, galaxy groups and other wide-field treats.
For extremely wide views usually reserved for binoculars, use a 2"
diagonal and long focal length/ wide field 2" eyepiece. |
