Astronomy Telescopes Reflectors
On this page about astronomy telescopes, reflectors are the topic.
Reflectors, as the name implies, use mirrors to gather the light
from the aperture and reflect it to the eyepiece.
The eyepiece is often located near the front or top of the
scope giving the reflector a strange look and way of use
to those new to astronomy telescopes.
Some of the benefits of a reflector type scope follow.
Reflectors generally have the lowest cost per inch(or millimeter)
of aperture. So for the same cost as the other types of telescopes
you can get a larger aperture or objective lens size.
Having a larger objective lens allows your astronomy telescope
to gather more light so you can see more objects.
This will allow you to view deep-sky objects such as
nebulae and star clusters.
Of course reflectors are good for viewing the planets and moons
in our solar system, producing bright images.
Reflector telescopes do need to be aligned sometimes to keep
the mirrors in correct reflecting position. This is known as
collimation and is a fairly simple procedure.
Reflectors also need to be cleaned more often than their
cousins.
Here are some options for your first astronomy telescope
if you have decided on a reflector:
With reflector scopes a shorter focal length, basically the length of
the tube, gives a wider field of view. So you see more of the sky at
one time.
Use shorter tubes for deep sky observing, and longer tubes for viewing
the moon and planets. However remember that shorter tubes can cause
increased aberrations so keep the power magnification under 100 times.
