The telescope consists of three
main parts: optical tube assembly
(OTA) (), parallactic mount(), and
a tripod(3).
The optical tube is a basic
component of the telescope. It
includes all main optical units
such as an objective lens and an
eyepiece unit.
The telescope refers to the
refractors by the type of it’s optical
system. A parallel beam of light
enters the telescope tube and
using an achromatic objective
lens () is projected in the focal
plane of the eyepiece ().
For comfort observations the
eyepiece unit is inclined on 90°
relatively to the optical axis of the
telescope with help of flat diagonal
mirror (3).
Using a diagonal mirror allows to
get a direct image of objects with
their mirroring.
Using a telescope without the
diagonal mirror gives inverted
image.
A standard set includes an
eyepiece, a Barlow lens and a
bushing, which allow observing
celestial objects with various
power of magnification.
