Lunt 60mm H-Alpha Pressure Tuned Solar Telescope

The Lunt LS60THa Telescope is a Hydrogen-Alpha, or Ha, Solar Telescope. The refractor based system has a precision aligned singlet chromatic lens with a 60 mm aperture. The front singlet lens reduces by half the stray light of an achromat. It fully eliminates the possibility for on-axis coma, astigmatism, as well as decentering aberrations, and with the matched collimation lens set, provides a full spherically-corrected flat-field H-Alpha Solar Telescope.

The Lunt LS60THA-PT has an internal etalon with an innovative air-pressure tuning adjustment that produces a bandwidth of <0.7 Angstroms. This "Pressure Tuner" system allows for a better etalon adjustment than other systems. The pressure tuned system adapts the etalon to varying altitudes and atmospheric pressure for optimal performance wherever you are observing.

About the Drop-Down Choices for the LS60THA-PT:

The base model of the LS60THA-PT is pressure tuned and comes with a 6mm Blocking Filter (B600) and Lunt 2" Crayford Style 10:1 Dual Speed Focuser. The B600 blocking filter provides a ~4.5mm image when used with this solar scope and is a good choice if you are going to be using the scope visually. The Lunt focuser is solid and stable for most any application, has 10:1 dual focus knobs and an etched focusing scale on the draw tube to visually guide you to the best focus quickly. If that sounds good to you, just choose the first option (6mm Blocking Filter with 2" Crayford Focuser) and your price will remain as shown.

If you would like to upgrade to the Starlight Instruments 2" Feather Touch Focuser and/or the B1200 (12mm) Blocking Filter, just pick from the remaining choices in the drop-down. The B1200 is a worthy upgrade if you will be doing photography through the scope or you want a wider field of view visually. A Starlight Feather Touch focuser is always a nice upgrade! Either focuser should perform well but if you plan to ride heavy loads off the focuser then perhaps you should consider the Feather Touch, which can handle up to 5.5 pounds. The price of the telescope package will adjust depending on the blocking filter and focuser you choose.
