DSII Module with “Pressure Tuner” for LS80MT & LS100MT-Telescopes
Congratulations and thank you on your purchase of a Lunt Solar Systems instrument! 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. Please note the safety instructions in
the manual of your LS80MT or LS100MT telescope.
Handling
and
Cleaning
Please also note the relevant instructions in the manual of your LS80MT or LS100MT telescope. These also
apply to the DSII module.
The DSII Module with “Pressure Tuner” for LS80MT and LS100MT
Telescopes
The DSII module is an upgrade to the standard LS80MT and LS100MT solar telescope. The DSII module
contains a specially designed re-collimating and refocus lens set that will only work in the LS80MT and
LS100MT. The module contains a precisely tuned narrowband interference filter in a sealed cavity. This filter will
reduce the bandwidth of the LS80MT or LS100MT to <0.5 Angstroms. The DSII system utilizes our advanced
“Pressure Tuner” technology, allowing for easy tuning of the finest details.
The DSII module is designed to provide enhanced surface detail, allowing for higher contrast views of the
filaments and active regions. Some dimming of the prominence (edge) details will be noted due to the narrowing
of the bandwidth.
Attention: Because the DSII module is designed ONLY for use in LS80MT and LS100MT telescopes, and
in these telescopes all necessary energy filters are already installed, the DSII module has no extra
energy filters. Therefore never use the DSII module without a LS80MT or LS100MT telescope! IR and UV
radiation can damage your eyes when the DSII module is used without LS80MT or LS100MT telescope!
What is delivered with the system?
- DSII module for LS80MT and LS100MT telescopes
- Internal Etalon with “Pressure Tuner”
- 6 thumbscrews for easy installation and removal
- Shipping box with die cut foam insert
- Instruction manual
Okay let's get started...
Safety First!
- Always check any solar telescope before use. Do not use any telescope or filter that appears to be
damaged. Verify that all glass and filters are in place.
- The Blocking Filter diagonal or extension tube must always be used with the Lunt telescope or filter.
At first follow the instructions for your normal LS80MT or LS100MT telescope. If you have sharp focused the sun
you would tune the built-in H-alpha filter. Note of the position of the black handle of the Pressure-Tuner on the
brass cylinder.
Installing the DSII module at the telescope:
Take the LS80MT or LS100MT back from the mount, and put it on
a clean table. At the far end of the red housing with the Pressure-Tuner, you will find 3 screws that hold the
focuser. Unscrew the screws and remove the focuser.
