Lunt Solar Systems

The Lunt Solar Systems LS80THa/PT is a complete and dedicated solar telescope. A precision aligned ED refractor with a fully un-obstructed 80 mm optical aperture, this package provides a significant step up into the intermediate category of solar observing. The LS80THa/PT (PT = Pressure-Tuned) maintains 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.

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 location 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.

This LS80THa package is fully upgraded with the 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, allowing you to see the Sun’s weather in stunning high definition.

    This is one of the best imaging scopes I’ve used in the past 15 years for h-alpha close up images. The tri-band adaptability of the design makes it configurable to what ever view you are in the mood for. It delivers enough resolve and detail to show you the most tiny features on the Sun and gives you that “Wow” feeling every time you look through it. Its a pretty stout scope that requires a heavy duty mount but if you’re looking into a first class trip to the Sun this is definitely the only way to fly. The close up images this scope delivers are second to none, rich with action and packed with high resolution.

    Very good product!

  3. Rated 5 out of 5


    I had heard a lot of good things about the 80mm scope having really sharp optics and an even field and decided to order one. The single stack 80 is incredible. It provides a super even field of H-alpha detail across the disk and then some. It shows proms good and provides enough resolve to get pretty detailed close up images. I use mine mainly for imaging and so far it has given me some great shots. I would recommend this size scope to someone that wants a high quality “full disk” imaging scope and mid range close up scope. It really is a nice grab and go model that delivers.
