Lunt 80mm Crayford

 

Complete H-alpha Solar Telescope with 80mm aperture and <0.7 Angstrom bandwidth. Supplied with 2" Crayford focuser, new air-pressure tuning system and B1200 Blocking Filter, that provides less vignetting for imaging! The B1200 blocking filter is recommended as the minimum for imaging use with this focal length.

The Lunt Systems LS80THa is a complete Solar Telescope with 60mm aperture and 560mm focal length. An internal etalon with new air-pressure tuning adjustment allows for a <0.7 Angstrom bandwidth. This "Pressure Tuner" system allows a better Etalon adjustment than other systems. The “Pressure Tuner” system adapted the Etalon to varying altitudes and atmospheric pressures for always optimal performance. With the matched collimation lens set, the Lunt LS80THa is fully corrected for on axis coma, astigmatism and de-centering aberrations and provides a full spherically corrected flat-field Solar-Telescope. Blocking filter is the B1200, that provides less vignetting for imaging. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25" eyepieces and with a T2 camera connection. Fine adjustment is achieved with a 2" Crayford Focuser with 10:1 reduction.

Imaging. Lunt Solar Telescopes are capable of superb imaging results. However remember that these telescopes are designed to filter out all light except that in the very narrow H-Alpha wavelength. If you attempt to image using an unmodified DSLR, you will get a poor image. This is because the standard filter in a DSLR blocks H-Alpha wavelengths. It is recommended that only DSLR's with the standard filters removed or replaced with H-Alpha pass filters are used for best results.

We also recommend that in addition to Prime focus imaging by mounting the camera to the B1200 Blocking Filter directly, that eyepiece projection photography is tried for extreme close ups of the Sun. This can be achieved by using the B1200 Blocking Filter in conjunction with the Baader Hyperion eyepieces.

To mount the telescope you will require either the LS100 or LS150 dovetails. We recommend the longer version as this offers the chance of better balance.
