What do the specifications mean?
Optical tube focal length is simply a measurement
of the length of the optical tube. In other words,
this is the distance light travels in the telescope
before being brought to focus in you eyepiece.
For example, the Polaris 90 Refractor tube is
900mm long.
Primary mirror diameter (reflectors) or
Objective lens diameter (refractors) is how
big the mirror or lens is on your scope.
Telescopes are always described by how
large their primary mirror/lens is.
For example, the objective lens
on the Polaris 90 is 90mm or
3.5 inches. Telescopes come in
many different sizes. They can
be 70mm, 8 inches, 16 inches,
or even 3 feet in diameter. The
Hubble Space Telescope’s
primary mirror has a diameter
of 2.4 meters (that’s 7.8 feet
across!).
The focal ratio helps determine
how fast the photographic speed
of a telescope is. The lower the
focal ratio number, the faster the
exposure. F/5 is faster than f/10.
The slower the focal ratio, the longer
the exposure time is needed when a
camera is hooked up to the telescope.
For example, the Polaris 90 Refractor
has slow focal ratio at f/10. Sometimes,
astronomers use focal reducers to
make slow exposure telescopes have
faster focal ratios.
USE THE SPECIFICATIONS
TO CALCULATE THE
MAGNIFICATION OF YOUR
EYEPIECE
The power of a telescope is how
much it magnifies objects. Each
telescope has its own set of focal
lengths and, therefore, different
magnifications when used with
various eyepieces. For example,
the Polaris 90 used with the 25mm
eyepiece magnifies an object 36
times. The 9mm eyepiece used
with the Polaris 90 will magnify

- A correct collimation 21
- All meade polaris reflecting telescopes are optically aligned at the factory prior to shipment it is unlikely that you will need to align or collimate the optics after receipt of the instrument however if the telescope received unusually rough handling in 21
- Collimation alignment of optics reflecting models only 21

- Shipment it is possible that the optics must be re aligned for best optical performance in any case this alignment procedure is simple and requires only a few minutes the very first time the telescope is used take the time to familiarize yourself with the following collimation procedure so that 21
- The properly collimated aligned mirror system in the meade polaris telescope assures the sharpest images possible this occurs when the primary mirror and secondary mirror are tilted so that the focused image falls directly through the center of the focuser draw tube these mirror tilt adjustments are made with the secondary mirror assembly and the primary mirror cell fig 13 and will be discussed later 21
- Tissues or damage could result to the optics do not use a commercial photographic lens cleaner 21
- You will recognize a properly collimated instrument and can adjust the collimation yourself if necessary 21
