LUNT 130mm Solar Telescope - H-Alpha Pressure Tuned - LS130THa
View the Universe with the Lunt LS130Ha Telescope - Day or Night!
LS130THa Solar Telescope
The Lunt LS130THa solar telescope is a complete solar telescope. This refractor-based system has a precision-aligned triplet ED lens with a 130 mm aperture. Furthermore, the focal length is 910 mm, for an f/ratio of 7. Additionally, the coarse focus adjustment is made via a slide tube. While focusing is achieved with a high precision 2″ Starlight Feather Touch focuser with 10:1 reduction as standard equipment. Most importantly, an internal etalon with tune adjustment allows for a <0.65 Angstrom bandpass.
LS130THa Nighttime Telescope
This is our best telescope for either Solar or Nighttime viewing. Easily change from daytime viewing (through etalons) to nighttime viewing (without etalons) in minutes! This scope gives you the best of both worlds. You’ll see granular details of the Sun and the best nighttime views without visual anomalies we have made. Now you can use one telescope for all your celestial viewing!
True Doppler Tuning
Importantly, True Doppler Tuning allows for a shift into and away from the user, adding a 3-D like component to the viewing experience. To be sure, it has minimal effect on proms due to their location at the edge of the disk, but it does have an effect on filaments and likewise the active regions on the surface. Also 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. In this way following the filament through it’s structure toward you and away from you. Amazingly, this allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist. In addition the pressure tuning system provides an order of magnitude more precision to the tuning of the desired features.
