LS100THa/DSII Manual
Congratulations and thank you on your purchase of a Lunt Solar Systems DSII Module! 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.
If you are new to solar observing you may want to access our web page or Lunt Solar on Yahoo Groups to get information
from more experienced users as to the subtleties of improved performance for each type of instrument.
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 the factory 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.
Always be aware that you are viewing in direct sunlight. Take necessary precautions to protect yourself from
sunburn and heat exposure.
Handling
A Lunt Solar Systems solar filter or telescope houses many optical elements that are all pre-aligned and fixed at the
factory. There are no user serviceable parts inside the scope. The telescope or 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. Mis-handling 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 packaging. 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 buildup 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
