Images taken through a Lunt LS60THa pressure tuned solar telescope

The excitement of viewing our Star through a dedicated solar telescope is sure to provide many many hours of visual enjoyment and educational insights. This package is fully upgradeable at any time without ever having to go back to the factory. As the Sun becomes increasingly more active, you will appreciate that the instrument can grow right along with it.

The Lunt LS60THa Pressure Tuned Solar Telescope,   provides the basic essentials perfect for a first time introduction to solar observing, while also including the newest technology for fine tuning, allowing basic research of the Sun’s disk and some surface details.

Lunt LS60THa Pressure Tuned

True Doppler Tuning (Pressure Tuning) allows for a shift into and away from the user, adding a 3D-like component to the viewing experience. While it has minimal effect on proms due to their being at the edge of the disk, it does have an effect on filaments and active regions on the surface. While looking at a filament at the center of the Sun the user has the ability to Doppler shift from the base of the filament to the tip, following the filament through it’s structure toward you and away from you, allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist. The pressure tuning system provides an order of magnitude more precision to the tuning of the desired features.

  1. K. H. Cantoli

    Stopped by the Lunt facility in Tucson today and came home with an LS60THa. Thanks to Faye, Benjamin and the crew for the facility tour and help selecting a scope! My husband and I are both very impressed. Now if the Tucson heat would die down a bit so we can try out the new scope…. It should be great when we get back home to the San Francisco Bay Area.

    I’ve been using and loving my new scope every time I get a chance. Now I’m a Sun worshipper (of the scientific kind).

    A lovely instrument to behold
