LUNT 100mm Single Stack Solar Telescope – Choice of Blocking Filters – Feather Touch Focuser
The Lunt LS100THa solar telescope is a complete solar telescope. This refractor-based system has a precision-aligned doublet ED lens with a 102 mm aperture. Furthermore, the focal length is 714 mm, for an f/ratio of 7. Additionally, the course 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 <0.7 Angstrom bandpass.
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.
