LS40THa H-alpha Solar-Telescope
Telescope for solar observation in the H-Alpha wavelength. The H-alpha wavelength is the most impressive
way to observe the sun, here prominences at the solar edge become visible, filaments and flares on the
surface, and much more.
Included Contents:
- LS40THa telescope
- H-alpha unit with tilt-tuning
- Blocking-filter B500, B600, or B1200
- 1.25 inch Helical focuser
- Dovetail bar (GP level) for installing at astronomical mounts
- 1/4-20 tapped base (standard thread for photo-tripods) inside the dovetail for installing at photo-tripods
- Sol-searcher
Please note:
Please keep the foam insert from the delivery box. The optionally available transport-case for
the LS40THa (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 for purchasing the LS40THa telescope from Lunt Solar Systems! The easy
handling makes this telescope ideal for starting H-Alpha solar observation. Due to its compact dimensions it
is also a good travel telescope for the experienced solar observers.
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 telescope! 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 diagonal or
remove the filter itself not being aware of the integrated safety features of each.
The Lunt Solar Systems 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, or in the optionally available transport case item number
0554010. 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.
