LS50FHa Manual

 

Congratulations and thank you on your purchase of a Lunt Solar Systems solar filter or 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.

 

  

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 subtly 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 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.
