Lunt Solar Systems LS50THa Manual

Manual
LS50THα Telescope with Pressure Tuner
Congratulations and thank you on your purchase of a Lunt Solar Systems solar telescope! 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!
The Lunt Solar filter/telescopes are not interchangeable with competitor products.

Handling

A Lunt Solar Systems solar 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 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 system 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
center and working around the edge and off in one complete motion. Be firm, but do not rub. Blow lightly to help
remove residual solution before it "spots" the surface. Residual dust from the cloth can be blown off.
Consult your local dealer or call Lunt Solar Systems with any questions or concerns.
Do not use Acetone or strong degreaser type products, household cleaning agents, paper towels, tissues with
added scent or color (plain tissues only), or bleach or acidic products which will damage the anodized surfaces.
