This modular 80mm ED APO telescope is designed for observing and photographing the Sun in H-Alpha.
An optional Lunt conversion kit with R&P focuser (item number 0551330) is also available that enables you to fit a regular 2" Star Diagonal for night-time visual astronomy and astrophotography.

Solar observing in H-alpha:
The LS80MT/B1200 is a complete telescope for observing the sun in H-alpha light. Observing the sun in H-alpha wavelength reveals protuberances at the sun's edge, filaments and flares on the surface, and much more.
The B1200 blocking-filter is a good for visual solar observing. Solar imaging is also possible using cameras with small sensors. (Lunt recommend their LS80MT with B1800 blocking-filter for use with large camera sensors).
The blocking filter is fitted into a star diagonal that accepts 1.25 inch eyepieces and includes a T2 camera connection.
An internal Etalon filter achieves a bandwidth of <0.7 Angstrom.
The telescope also features Lunt's innovative air pressure tuning system that provides a clean homogeneous image. Tuning is achieved by slightly changing the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, making it easy to tune to the H-alpha line.
Other features include a permanently protected Etalon that resists erosion, collimateable lenses for optimum performance and fine focus adjustment via a 2" Crayford focuser with 10:1 reduction.
Observing the starry night sky:
The H-Alpha Etalon system can be removed from the telescope in a few easy steps thanks to its modular design. An optional Lunt conversion kit with R&P focuser (item number 0551330) is available that enables you to fit a regular 2" Star Diagonal for night-time visual astronomy and astrophotography. When used this way the telescope's unobstructed 80mm ED doublet optics provide clear views with high contrast and minimal chromatic aberration.

More applications:
With additionally available accessories the LS80MT offers even more possibilities!
Double-Stack
The LS80MT telescope can optionally be upgraded with the additionally available double-stack module DSII/SFPT (item number 0551395). The DSII system is a internal double-stack module. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Therefore much more details on the solar surface will become visible.
Solar observing in White-Light
If the H-alpha unit has been removed, of course either a sun filter to be installed in front of the objective, or a Herschel-wedge at the focuser can be used to observe the sunspots in White-Light.
Solar observing in Ca-K wavelength
Certainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS80MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.
This makes the LS80MT a completely universal usable ED Apo telescope of very good quality!
