Orion Glass Solar Filters

DANGER! Viewing the Sun through any optical instru-
ment without a correctly inspected and installed solar
filter can cause immediate, permanent eye damage and
blindness!
Solar viewing is safe only if you understand the potential
dangers and follow all directions. Read these instruc-
tions carefully and save them for future reference. Do
not allow children or inexperienced adults to use the
telescope or solar filter unattended.
DANGER! DANGER! DANGER! Always cover your tele-
scope if you leave it outside during the daytime! An
open telescope, of any design, can burn the telescope
or surrounding areas if an unfortunate alignment of the
telescope and the sun occurs; any telescope will con-
centrate sunlight to very high temperatures.
Mounting the Solar Filter
The inside of the filter cell will either be lined with foam tape or
unlined, depending on the telescope or binocular it has been
designed to fit. The filter should fit just tight enough to keep
from slipping off when the telescope or binocular is pointed
down. If your filter is too loose, it can be custom fitted by apply-
ing the supplied foam tape inserts on the inside rim of the cell.
On some models, you may need only one insert to achieve a
snug fit. On others, more than one may be required. The filter
should not fit too tightly or the optical surfaces may be distorted
due to stress on the cell.

DANGER! DANGER! Always
use a solar filter AND a light
shroud when observing the
Sun with a Truss Tube tele-
scope! A solar filter will
protect your eye and the tele-
scope when you are pointed
directly at the sun; but if the
telescope is pointing slightly
off axis (off-target), direct/
unfiltered solar energy could
be focused on interior por-
tions of the telescope.
Orion solar filters also feature three equidistant nylon set
screws that, when tightened, ensure a secure fit to the tele-
scope or binocular being used to observe solar activity.
NOTE: Do not solely rely on the nylon thumbscrews to
keep your solar filter safely installed. If your filter is too
loose, please use the supplied foam tape inserts to create
a friction fit. The nylon thumbscrews have been provided
as a "lock-down" safety feature which should be used in
addition to the foam lining.
Using the Solar Filter
1. Check the filter's optical surfaces for any possible
damage before each use. The view through your
telescope should be comfortable and not appear
excessively bright. Stop looking immediately if the view
is excessively bright.
2. Check for any pinholes. Even one bright pinhole
could degrade the image quality. See "Inspection &
Maintenance."
3. Keep the front of any finder scope covered if it is
not equipped with a solar filter. Better yet, remove
the finder altogether when observing the Sun. An
uncovered finder scope is dangerous to look through.
Even if you do not look through it, unfiltered sunlight
may melt internal parts of a finder scope.
4. ALWAYS use a light shroud and a solar filter if you are
using a truss tube telescope.
5. Aim the telescope at the Sun by moving your tube
assembly until the smallest shadow is cast on the
ground.
6. Allow the telescope and filter to equalize to outside
temperature for at least 15 minutes.
7. Direct sunlight may warm the tube assembly enough
to cause internal heat currents that can degrade image
quality, especially on dark-colored telescopes. Cover
the tube assembly with a light-colored cloth to help
avoid this.
8. If possible, do not view over pavement or buildings.
Viewing over grass will help avoid surface heat
currents.
9. Point the telescope away from the Sun before removing
the solar filter! Removing the filter while the telescope
is aimed at the Sun is dangerous if anyone is looking
into the eyepiece, and can damage the telescope if left
pointed at the Sun for too long.
10. "Ghosting" may occur with some compound telescopes,
such as Schmidt-Cassegrains, which incorporate larger
secondary mirrors in their design. If this is a problem,
simply tilt the filter slightly to move the "ghost" outside
the field of view.
