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 other edges of the plastic
filter cell. Avoid making contact with the filter material. Do not use
any cleaning chemicals or brushes to clean this material. If you need
to clean dust, use compressed air to blow it clean. Small smudges or
fingerprints will have no effect on the performance of the filter. When
not using the filter, make sure the safety cap is installed
INSTALLING THE FILTER
Before installing your filter, hold the filter up to a bright light source
to inspect the surface (Figure 1). If you see holes or damage to the
surface of the filter, do not use it. Each filter is based on the design
of your telescope's lens cap and should fit snugly. Simply remove
the lens cap from your telescope and replace it with the solar filter.
