SOLAR WARNING
Even though your EclipSmart solar filter is equipped with ISO
certified material that allow safe direct observation of the
Sun, there are still some important rules you should follow
when solar observing:
• Never look directly at the Sun with the naked eye or with a telescope
unless you have the proper solar filter. Permanent and irreversible
eye damage may result.
• Never use a telescope to project an image of the Sun onto any
surface. Internal heat build-up can damage the telescope and any
accessories attached to it.
• Never use an eyepiece solar filter or a Herschel wedge. Internal heat
build-up inside the telescope can cause these devices to crack or
break, allowing unfiltered sunlight to pass through to the eye.
• Do not leave the telescope unsupervised, especially when children
or adults unfamiliar with the correct operating procedures of your
telescope are present.
HANDLING THE FILTER
When handling the filter, hold it by the outer edges of the plastic filter
cell. Do not touch or make contact with the filter material. Do not use
any cleaning chemicals or brushes to clean the material. If you need to
remove dust from the filter, use compressed air to blow it clean. Small
smudges or fingerprints will not affect the filter's performance. When
you are not using the filter, always store it in its original box.

INSTALLING THE FILTER
Before installing your filter, remove the protective cap and inspect
its surface (Figure 1) carefully under a bright light source. If you see
holes or damage to the surface of the filter, do not use it. When you
are ready to install the filter, remove your telescope's lens cap and
replace it with the solar filter. Each filter is based on the design of
your telescope's lens cap and should fit snugly.
Your filter fits over the lens shade of the telescope; it's held in
place with three supplied nylon thumbscrews. Simply insert the
three safety screws into the threaded holes on the side of the filter
and tighten with just enough force to secure the filter in place. Do
not overtighten.
REMOVE THE FINDERSCOPE
When observing the Sun, you should completely remove the optical
finderscope from the telescope. Allowing the Sun to shine through
an optical finderscope will result in a focused beam of sunlight
that can cause burns or permanent damage to the finderscope.
Never rely on the lens caps to stay secured to the finderscope. If
you're concerned you won't be able to point the telescope at the
Sun without a finderscope, don't worry. Locating the Sun without a
finderscope is very simple, as we'll explain in the next section.
LOCATING THE SUN IN THE TELESCOPE
Without directly looking at the Sun, turn the scope so that the
filter is pointing in the Sun's general direction. Next, turn around
and look at the telescope's shadow on the ground. Move the scope
to adjust its position until the telescope tube's shadow appears
perfectly round. If you are slightly off, the shadow will appear
oval or elongated. When you have pointed the telescope correctly,
the Sun should be within the field of view of your lowest power
eyepiece. If it is not, look through the eyepiece and slowly move
the scope in a circular pattern. You should find it in no time.
The Sun will appear as an orange disk in the eyepiece. Use your
telescope's focusing knobs as you normally would until the edge
of the solar disk appears sharp.
