Product Info

Manufacturer Description

The Lunt Solar Systems LS80THa/PT (pressure tuned) is a complete and dedicated solar telescope. A precision aligned ED refractor with a fully un-obstructed 80mm optical aperture, this package provides a significant step up into the Intermediate category of Daytime Solar Observing. The LS80THa/PT 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 observable.

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 prominences 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, 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.

      5.0 LS80 Single Stack

      Pros:

      Cons:

      Comments:

      I have a Lunt LS50 double stack that I have owned for about 2 years now, I have been saving for the LS80. Finally got enough for it and with my previous good relations with Agena I ordered it when I saw they had one.
      The scope arrived double boxed, well actually triple boxed since it was also in an aluminum carry case with form fitted foam.
      The scope is very well made and just feels top quality. It is a good 9 pounds but still works on my Orion Alt Az mount as well as my EQ Skyview pro. For imaging I am using a ZWO ASI174mm and ASI120mm.
      Naturally since getting it we have had very little sun and when the sun has been out the wind has been gusting to 35-40 mph.
      Imaging I have been having some issues, not with the scope but with the cables for the camera and Newtons RIngs. When I tame those I am getting very good results.
      Visually the proms and the limb of the sun are much better than the LS50 you could get some spicule detail and the proms were great, however the surface of the sun on the LS50 double stacked shows more detail, at least to me with the limited time I have been able to observe. Today there were two filaments showing in the LS50DS but I couldn't make them out in the LS80, but I have been trying to play with the pressure tuner on the 80 to see if I could dial them in.
      I am considering the double stack unit for the LS80 for visual and outreach.

      For using cameras and bino-viewers the LS80 works great, the monkeying with it like I have to with the LS50, you just put them into the diagonal and you are good to go. The view through the bino viewers is really something! For the cameras the blocking filter (diagonal) has plenty of back focus, you can pull it out a long way, I had 3 inches showing and still enough in the scope to hold it firm.

      So far I am impressed.

      Pros
      Build quality
      Ease of use
      ability to use various accessories in 1 1/4 diagonal
      Imaging

      Cons
      heavier than the LS50 and bulky, although better than the 100
      visually not as much contrast as a double stacked unit.

      Bottom Line: Would you recommend this item? Yes
      Was this review helpful? Yes / No
