αα 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
- Internal Etalon with Pressure Tuner
- Blocking filter B400 or B600

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.

Using the telescope:
Note:
- Please check before the telescope is removed from the transport box that the locking of the blocking filter is
applied. Maybe it can happen elsewhere, that when removing the telescope the block filter slip out of the focuser
and fall off.
Safety First!
- Always check any telescope before use. Do not use any telescope or filter that appears to be damaged.
- The Blocking Filter diagonal must always be used with the Lunt telescope.
Attach the telescope and clamshell to your mount of choice. There is a ¼-20 threaded hole on the underside of
the clamshell. Attach the scope directly to a photographic tripod, or attach a Vixen-style dovetail plate to the
clamshell for installing at a astronomical mount.
Slide the Blocking Filter into the focuser and lock it down with the thumb screw. Insert a low power eyepiece into
the blocking filter. A 25 mm eyepiece is a good choice for a large field of view.
Point the telescope to the Sun. You can use the shadow of the front lens cell cast by the Sun onto the clamshell
of your telescope. Center the shadow and you should be pretty close. Never attempt to use a conventional finder
scope to locate the Sun! Look through the eyepiece. Do you see a fuzzy red ball? If not, make sure you have
removed the dust cap from the front and check your alignment to the Sun. If the Sun is still not in the field of view
of your eyepiece, move the telescope around a little while you are looking through it. Be patient, you will find it!
Once you do, center the Sun and, if you have one, adjust the Sol-Searcher so that it is correctly aligned to your
scope.
Now its time to focus. Your goal is to get the edge of the Sun as sharp as possible. Focus is achieved using the
helical style eyepiece focuser.
Tuning: Here is where the magic begins. On the side of the scope is a large black cylinder on a brass barrel.
This cylinder is the Pressure Tuning system for the LS50THaPT. The black handle of the cylinder has a short
start-thread attaching it to the brass cylinder. Unscrew the black handle completely. There may be some
resistance and a faint “popping” sound. Thats normal when adjusting pressure for your altitude. Carefully install
the handle onto the cylinder, engaging the threads about one turn. While looking through the eyepiece, gently
turn the black handle clockwise onto the cylinder. There will be little resistance at first, but as the pressure in the
cylinder builds, the resistance increases slightly. As you turn the cylinder, centering the 656.28 nm wavelength
on- band, you should see features come into view. Continued tuning will result in the wavelength shifting past
656.28 nm, and details will begin to disappear. Fine-tune for the best images.
A few details regarding the pressure tune system. The amount of pressure being supplied to the etalon cavity is
minimal. It is the equivalent of going from -150m below sea level to about 3,000m. Or around 0.1 Bar, there is no
risk of explosion. We are dealing with only a fraction of 1 atmosphere. When not in use we recommend that you
release the pressure by simply backing off the black handle from the cylinder body. If the system unthreads
completely, simply thread it back on 1 turn. It is not necessary to re-set the system every time it is used. Re-
setting may only be required if the system has been sitting for a long period of time.
