Lunt Solar 80 mm H-Alpha Pressure Tuned Telescope
with DSII Internal Double-Stacking Module




The Lunt LS80THa Solar Telescope provides all that you need for spectacular views of our Sun at a bandpass of <0.7 Angstrom. It is a precision-aligned ED refractor with a fully unobstructed 80 mm optical aperture. When the included Internal Double Stacking Module is installed, it will reduce the effective bandpass down to <0.5 Angstrom. This provides extra resolution and improved contrast of many solar details and phenomena. The DSII eliminates the need for an external double stack etalon, reducing cost and eliminating obstructions. The system is 100% unobstructed.



All Lunt Solar Systems LS80THA H-Alpha Telescopes include pressure tuning, as does the DSII internal double-stacking module. 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.




Lunt LS80THA-DSII Telescope Specifications:




  • Telescope: Single Interference Etalon Solar Telescope


  • Tuning: Internal Pressure Tune (Doppler True Tuning) for Telescope & DSII


  • Scope Aperture: 80 mm


  • Focal Length: 560 mm


  • F Ratio: F/7


  • Bandpass: <0.5 Angstrom @ 656 nm


  • Focuser: 2" Crayford or 2" Feather Touch (Choose from Dropdown)


  • Blocking Filter: B1200 or B1800 (Choose from Dropdown)


  • Mounting: Integrated clamshell style with 1/4-20 tapped base


  • Includes a Lunt Dovetail Bar for mounting


  • Color: Pearl White with Black and Red accents


  • Includes Lunt DSII Double-Stacking Module


  • Includes a Sol Searcher solar finder


  • Includes a hard carrying case


  • Includes a Lunt Zoom Eyepiece (model LS7-21ZE)


  • Includes dust cap




About Your Drop-Down Choices:



The base model of the LS80THA-DSII comes with a 12mm Blocking Filter (B1200) and a Lunt 2" Crayford Style 10:1 Dual Speed Focuser. The B1200 blocking filter provides a ~4.5mm image when used with this solar scope and is a good choice if you are going to be using the scope visually. The Lunt focuser is solid and stable for most any application, has 10:1 dual focus knobs and an etched focusing scale on the draw tube to visually guide you to the best focus quickly. If that sounds good to you, just choose the first option (12mm Blocking Filter with 2" Crayford Focuser) and your price will remain as shown.



If you would like to upgrade to the Starlight Instruments 2" Feather Touch Focuser and/or the B1800 (18mm) Blocking Filter, just pick from the remaining choices in the drop-down. The B1800 is a worthy upgrade if you will be doing photography through the scope or you want a wider field of view visually. A Starlight Feather Touch focuser is always a nice upgrade! Either focuser should perform well but if you plan to ride heavy loads off the focuser then perhaps you should consider the Feather Touch, which can handle up to 5.5 pounds. The price of the telescope package will adjust depending on the blocking filter and focuser you choose.
