What is a
New Technology Telescope?
The New Technology
Telescope (NTT) is an altitude-azimuth (alt-az) Newtonian with folded
optics and Go-To electronics. The NTT-40 is a 1 meter or 40"
(f/4)
system suitable for both visual work and short-exposure photography (no
field de-rotation). It includes the Vixen SkySensor 2000-PC computer control,
open Serrurier truss rod design, compact size and JMI's celebrated quality
construction. (See the April 2000 Sky &
Telescope magazine, page 56, for a review of the SkySensor 2000-PC.)
