Lunt - 60mm Ha Telescope w/ B600 with Pressure Tuner

The LS60/Ha is a complete Solar Telescope. The refractor based system has a precision aligned singlet
chromatic lens with a 60mm aperture. The front singlet lens reduce half the stray light of an achromat, fully
eliminate the possibility for on axis coma, astigmatism, decentering aberrations and provides with the matched
collimation lens set a full spherical corrected flat-field Solar-Telescope. The focal length is 500mm
providing a ~4.5 mm image through a 6mm blocking filter. Fine adjustment is achieved with a Crayford style
focuser or feather touch focuser with 10:1 reduction standard. An internal etalon with tune adjustment allows
for a <0.8 Angstrom bandpass.
