This is a Lunt Solar Systems 130 mm Ha Solar Telescope with a B3400 Blocking Filter. It also has an internal Ha Etalon with Lunt's Pressure Tuner, and a Feather Touch Focuser w/ 10:1 fine focus adjustment. The telescope OTA uses an advanced Triplet 130 mm apochromatic objective to guarantee the best image performance, either as a solar telescope, or (if/when converted) as a nighttime telescope.
The excitement of viewing our Star through a solar telescope will provide 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 user has the ability to upgrade this telescope to Double-Stacking, as well as add other, optional accessories they might wish to use for either solar observing or nighttime observing. For a fully portable travel scope with the versatility to adhere to all of your astronomical viewing needs, this newly designed ApochromaticTriplet refractor is the wise choice. With an easily-convertible design system, the LS130THa lets you explore daytime (solar) as well as nighttime skies!
For a fully portable travel scope with the versatility to adhere to all of your astronomical viewing needs this newly designed ApochromaticTriplet refractor is the wise choice. With an easily-convertible design, the LS130THa lets you explore daytime (solar) experiences, as well as nighttime skies! This All-In-One 130 mm Ha (or Nighttime) Telescope from Lunt Solar Systems will be one of your best astronomical investments!
With increased resolution compared to smaller apertures, the LS130THa is sure to delight, allowing viewers to delve into the fine details and surface phenomena of our ever changing Sun using its tried and true Doppler Tuning system. This telescope's 130 mm aperture enables higher magnification due to increased resolution, highlighting the fine intricacies of the Sun in your eyepiece or on your screen. Users have the ability to easily switch between configurations. This Lunt Solar 130 mm Solar Telescope features a convertible capability that is unlike any other. With a few twists of a screw, you can go from enjoying the Sun’s surface views to viewing distant objects in the night sky. The LS130THa is capable of converting from Hydrogen Alpha, to Calcium-K, to White Light solar, or to standard nighttime viewing, without difficulty. Simply choose the accessories you need to meet your requirements, interchange as directed and you are ready to view!
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 can Doppler shift wavelength 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 Lunt pressure tuning system provides an order of magnitude more precision to the tuning of the desired features than tilt tuning can.
