Carefully apply the ring, making sure to center it against the mark Since you have
the primary mirror out of the scope anyway, check it to see if it needs to be
washed [Hack #34]. After washing the mirror, if necessary, reinstall the mirror in
its cell ...

Next, you must remove the primary mirror and mark the precise center of the
mirror. Remove the three screws on the sides of the primary mirror cell, the black
metal ring on the rear of the scope. Be careful to hold the mirror cell as you

The Incredible Story of Telescopes
The primary mirror is the most important part in a telescope. The primary mirror
needs to be big enough to collect a lot of light. However, it cannot be so heavy
that it sags or bends, or so thin that it changes shape in the wind. Primary mirrors
are ...

In my own 250-mm Newtonian, this fan sits behind the primary mirror. However, a
slightly better solution is to employ additional filtered fans in the side of the
telescope tube, blowing air across and sucking air out of the region just in front of
the ...

2.2.1 Significance of Lightweight Mirrors for Telescopes The primary mirror is the
most important component of an optical telescope. Its surface should maintain
high accuracy under the telescope operating conditions. The weight and cost of ...
Secondary mirror Primary mirror Eyepiece □ Figure 6-6 (a) A refracting
telescope uses a primary lens to focus starlight into an image that is magnified by
another lens called an eyepiece. The primary lens has a long focal length, and

Newtonian Telescope Since a reflector with its secondary mirror has a second
principal optical component, in contrast to a refractor, three alignment operations
are required per se: for the focuser, secondary mirror, and primary mirror.

Observing Variable Stars, Novae and Supernovae
Collimating a Newtonian reflector of focal ratio less than f/6 The lower the focal
ratio of the primary mirror, the more critical is the collimation of the telescope. So,
if we are to get the best results, we should use a refined technique to achieve the
...
