Telescope with Pressure Tuner
Complete Solar Telescope with 50mm aperture. An internal Etalon with advanced air-pressure tuning adjustment
allows for a <0.75 Angstrom bandwidth. The “Pressure Tuner” system adapted the Etalon to varying altitudes
and atmospheric pressures for always optimal performance. Blocking filter is the B400 or the B600. The star
diagonal in which the blocking filter is installed, is equipped as standard for 1.25" eyepieces. Fine adjustment is
achieved with a non-rotating Helical focuser.
What is delivered with the system?
- H-alpha telescope with 50mm aperture

Please note:
Please keep the foam insert from the delivery box. The optionally available transport-case for the
LS50THa (item number 0554010) is not supplied without such a foam insert, the original foam insert from the
delivery box fits exactly into this transport-case.
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.
Safety Information:
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!
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 blocking-filter diagonal
not being aware of the integrated safety features of it.
The Lunt Solar filter/telescopes are not interchangeable with competitor products.
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 box. 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.
