60mm H-ALPHA PRESSURE TUNER + B1200 + FEATHER TOUCH DOUBLE STACK
The LS60THa is a complete Solar Telescope. The refractor based system has a precision aligned singlet chromatic lens with a 60 mm aperture. The front singlet lens reduces the stray-light over an achromat by half. With the matched collimation lens set, it also fully corrects for on axis coma, astigmatism and de-centering aberrations and provides a full spherically corrected flat-field Solar-Telescope. The focal length is 500mm providing a ~4.5 mm image thru a 12mm blocking filter. Fine adjustment is achieved with a Feather Touch 2" focuser with 10:1 reduction. Adding the front-mounted unobstructed etalon allows for even shorter bandpass views.
An internal etalon with pressure tuner adjustment allows for a <0.75 Angstrom bandpass, or <0.55 with the front-mounted etalon.
