About Your Telescope
This is a Newton type Reflector Telescope. This design was invented in the
early 1660’s by James Gregory, a Scottish mathematician. It was further
developed by Isaac Newton, and was used in the development of Newton’s
book Optics which was published in 1704. Because of Newton’s stature in the
history of science, and the importance of his book, this telescope design is
now referred to as a Newton type reflector.
Earlier telescopes, such as the one used by Galileo simply consisted of glass
lenses mounted in a tube. Gallein telescopes have a tendency to separate
light into spectral components (rainbow-like colors) which make observations
difficult.
By using a mirror reflector in the light path the spectrum separation is reduced
and more precise observations can be made with a Newton-type reflector
telescope. Please see the diagram below.
Selecting a viewing location
For best viewing, find a location away from air pollutants, mist and fog
which has little light in the area.
5.
When done viewing, remove the Eyepiece, Barlow Lens and Sleeve, and put
them in a safe place. Replace the Lens Cover (12) on the telescope. Detach
the telescope from the tripod and store in a safe place.
NOTE: If viewing for a long time or viewing objects very far away, you will
have to periodically readjust the direction of the telescope. This is because of
the rotation of the Earth on its axis.
