 This
114mm (4.5") short tube catadioptric equatorial reflector telescope with 1000mm
focal length is the most popular size telescope for the more serious beginning
or intermediate level astronomy enthusiast, and for good reason. The large light
gathering power of this 4.5" telescope makes it ideal for deep-sky observation
of galaxies, star clusters and nebulae, as well as lunar and planetary
observing. This makes for a very useful and versatile instrument that can take
an observer from the very first time looking through a telescope's eyepiece,
through years of observing interesting subjects near and far in the night sky.
It also delivers great views of mountains, valleys, and many other features of
the world around us.
This short tube version of the 4.5" telescope offers more portability than the
standard longer tube without sacrificing power or performance. The short tube of
this model is only 16 1/2" long and has a built-in correction lens, giving it
all the focal length of the standard model, while reducing aberrations and
without losing power
needed to enjoy night sky observation.
