  • The first step into intermediary solar observing, the Lunt Solar Systems LS80Tha Pressure Tuned Hydrogen-Alpha Telescope comes with a precision aligned 80mm ED doublet lens.
  • Internal etalon system with pressure tune adjustment that allows a maximum of <0.7 Angstrom bandpass. Focal length is 560mm providing an image scale of 408.
  • The Lunt 80mm H-Alpha Telescope has a focal length of 560mm, and includes includes a 18mm blocking filter for a larger field of view.
  • The LS80THa PT includes a 2" dual speed 10:1 Crayford-style focuser, an integrated clam shell mounting ring, Sol Searcher Finder, Lunt Zoom Eyepiece and a foam-lined case.


Lunt Solar Systems LS80THa Pressure Tuned H-alpha Telescope

Now introducing the Lunt Solar Systems LS80/Ha H-Alpha Telescope! The perfect telescope for the intermediate solar observer. Want something more than your current 40mm set up but don't want to full tilt on your budget? This is the scope series for you!

But there's more than just a pretty view... You can achieve coarse focus adjustment with a slide tube, and then fine adjustments to focus are accomplished via the included dual-speed Crayford style focuser with 10:1 reduction. Its clam shell mount is compatible with most tripods and mounting holes are all part of the Lunt Solar Telescope System.... Right down to the stylized white pearl paint with anodized black trim and included foam lined hard case!

True Doppler 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 thru its 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. No one brings you closer to our nearest Star than Lunt Solar Systems... The next generation of Solar Instrumentation.

The LS80 Ha Telescope PT is 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 LS80THa 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 double stack etalon reducing cost and eliminating obstructions. The system is 100% un-obstructed. The band pass is reduced to <0.5 Angstroms. See the Sun's weather in stunning high definition.

Lunt Solar Systems creates their line of h-alpha solar telescopes in Tuscon, Arizona. They have have put together a group of experienced solar enthusiasts who are looking forward to energizing the hobby with a continued commitment to advancing technologies, pride in quality, and the highest level of customer care. These are names you'll recognize, including Andrew Lunt with 20 years of optical design, Markus Ludes with his extensive knowledge of telescope design, Manny Serrano as a design engineer and Brian Stevens assembling, repairing and troubleshooting etalon systems. And newly designed etalon systems are what it's all about.... Some of their new products will range from an entry level 50mm etalon filter through to a 160mm Lunt Solar Telescope System using different components... One that's less thermally sensitive and far less prone to de-contacting.
