Our E-Series Safety Film Solar Filters are a low cost but completely safe alterna-
tive to our aluminum cell and glass lters. They can be used on telescopes, bin-
oculars, monoculars, cameras and nder scopes to safely view and photograph
the Sun. Unlike some other solar lters, the black/silver polymer used in E-Series
solar lters will provide a pleasing natural yellow-orange image of the Sun. The
actual ltering properties are protected within the polymer itself.
This lter material (ND5 density) transmits less than 0.001% of sunlight through
the telescope. That might not sound like much, but it’s just enough to see the
Sun in its full glory while keeping your eyes safe from its harmful, intense
radiation. Do not use a lter that shows any form of defect, such as pinholes or
scratches. Please contact us for further return instructions. All solar lters are
covered by a limited liability warranty from defects in material and workmanship.
DANGER! Viewing the Sun through any optical instrument without
a correctly inspected and installed solar lter 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 instructions carefully and save them for future reference.
Do not allow children or inexperienced adults to use the telescope or solar lter
unattended.
How to Size a Filter to Fit Your Telescope or Binoculars
Your solar lter cell ts over the front of the telescope, nder scope, or binocu-
lars. When selecting a lter for your instrument, measure the outside diameter
(O.D.) of the tube where the lter will be installed and choose the lter size with
inside diameter (I.D.) slightly larger than the tube's O.D. Do not choose a lter
the same size as your O.D. This will be too tight and not allow room for the felt
lining that you will use to snugly t the lter to your instrument. You want a snug
t to prevent the lter from accidentally slipping off while in use, which could
cause serious eye damage. One or more strips of adhesive felt are included with
the lter. Cut one or more small strips as needed and apply to the inside of the
lter cell (remove the backing to expose the adhesive) to achieve a secure t.
Using the Solar Filter
1. Check the lter’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. Keep the front of any nder scope covered if it is not equipped with a solar
lter. Better yet, remove the nder altogether when observing the Sun. An
WARNING: Never look directly at the Sun through your telescope—
even for an instant—without a professionally made solar lter that
completely covers the front of the instrument, or permanent eye
damage could result. Young children should use this telescope only
with adult supervision.

uncovered nder scope is dangerous to look through. Even if you do not
look through it, unltered sunlight may melt internal parts of a nder scope.
3. To aim a telescope with solar lter installed at the Sun without aid of a nder
scope, you can use the shadow cast by the telescope as a guide. Point your
telescope in the general direction of the Sun, and watch the shadow cast by
the telescope tube on the ground. Move the tube gradually back and forth,
up and down until the shadow is the smallest it will get. The Sun should then
be visible in the eyepiece eld of view.
4. Allow the telescope and lter to equalize to outside temperature for at least
15 minutes.
5. 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.
6. If possible, do not view over pavement or buildings. Viewing over grass will
help avoid surface heat currents.
7. Point the telescope away from the Sun before removing the solar lter!
Removing the lter 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, unltered, for too long.
CAUTION
Do not use a filter that shows any form of defect such as pinholes
or scratches. If you see or suspect a defect, please contact us for
return instructions.
Observing Solar Eclipses with E-Series Filters
Whether using a telescope or binoculars for viewing a solar eclipse, there are a
few things to keep in mind:
1. Make sure the solar lter ts snugly on the front end of your instrument. For
binoculars, you'll need one lter over each of the two front lenses.
2. During all of the partial phases of a solar eclipse, the solar lter(s) must be
covering the front of your instrument.
3. Only during the brief "totality" portion of a total solar eclipse - when the
Moon completely covers the Sun's disk - is it safe to remove the lter and
view without it.
4. Be ready to stop viewing and re-install the lter the moment the rst glimmer
of the Sun's disk re-appears, signaling the end of totality.
Solar Photography
E-Series Safety Film Solar Filters can be used for both visual observing and
photography. By attaching a camera body to a telescope, in effect using the
scope as a telephoto lens, you can take striking photographs of the Sun. Only
attempt this if the telescope is equipped with the proper solar lter.
