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.
