Filter System
Congratulations and thank you on your purchase of a Lunt Solar Systems solar filter! The Lunt Solar systems are
a new generation of solar viewing instruments utilizing the most current technologies to provide the highest
quality contrast and resolution in their class.
Warning
There are inherent dangers when looking at the Sun thru any instrument. Lunt Solar Systems has taken your
safety very seriously in the design of our systems. With safety being the highest priority we ask that you read
and understand the operation of your telescope or filter system prior to use. Never attempt to disassemble the
system. Do not use your system if it is in someway compromised due to mishandling or damage. Please contact
our customer service with any questions or concerns regarding the safe use of your instrument.
Never look at the Sun with your naked eye or with a telescope that is not specifically designed to do so.
Permanent and irreversible eye damage may result!
Check that all filters are installed correctly
and are free of any surface contamination that may compromise
performance and/or potentially damage the surface of the optic when exposed to the Sun. i.e.: fingerprints.
Perform a routine safety check before each viewing session.
Never leave the solar telescope unsupervised while pointed at the Sun. People who are not familiar with
the correct operating procedures of the system may inadvertently replace the diagonal or remove the
filter itself not being aware of the integrated safety features of each.
The Lunt Solar filter/telescopes are not interchangeable with competitor products.
Handling
A Lunt Solar Systems solar filter houses many optical elements that are all pre-aligned and fixed at the factory.
There are no user serviceable parts inside the filter. The filter should never be taken apart. This will not only void
your warranty leading to costly repairs, it can only serve to further damage the instrument and compromise its
safety.
Most Lunt Solar Systems filters and telescopes house a delicate optical element referred to as an Etalon. These
Etalons are suspended in the filter housing in an effort to both protect it and isolate it from outside influences,
which could de-tune the Etalon filter. Extensive research has been done to assure the best performance of what
is essentially the "heart" of the system while protecting it from the day-to-day bumps, jarring, and vibrations of
normal use.
However, the instrument should never be subjected to shock due to being dropped. Mishandling of the filters
system will cause the Etalon to de-contact (not covered under warranty) and will render the instrument useless
until repaired.
The instrument should be stored in its original case. As with any precision optical instrument it should be kept in
as low a humidity area as possible.
With proper handling and care the filter should last a lifetime.
Cleaning
As with most telescopes and equipment there will be a build up of dust and debris on the lens and mechanical
components after sitting out all day. For those who are familiar with cleaning telescopes we recommend you use
the same techniques. For those who are new to the care of these instruments we can offer the following
guidelines:
Blow off loose dust and dirt using a clean dry air source at low volume. Do not use shop compressed air, which
contains oil and will further contaminate the instrument. Stubborn particulates can be brushed from the surface
with a static free lens brush. Use gentle sweeping motions. Fingerprints and smudges can be removed using
lens tissue or a Kleenex type tissue product. Fold the tissue or cloth to make a "pad", apply a cleaning product to
the end of the pad dampening it evenly (do not apply solution to the lens), wipe in circular motion starting at the
