The LS80T/PT (pressure tuned) is a complete and dedicated Solar Telescope with an Image Scale of 408.  Image scale is calculated by the effective image size at the focal plain and the clear aperture of the scope.  A precision aligned ED refractor with a fully un-obstructed 80mm optical aperture. This package provides a significant step up into the Intermediary category of Daytime Solar Observing, Maintaining the most advanced technology of Doppler True Tuning for fine adjustment of the center wavelength, allowing research of the Sun’s disk and surface details at increased image scale.  Prominences, flares, super granulation, filaments, and active regions will be observed.

The LS80T package is fully upgradeable with several options including the NEW evolutionary Dual Internal Stack Etalon System (DSII). The DSII eliminates the need for an external doublestack etalon reducing cost and eliminating obstructions. The system is 100% un-obstructed. The bandpass is reduced to <0.5 Angstroms. See the Sun’s weather in stunning high definition.
