There is a pure excitement of viewing our Sun through a dedicated solar telescope that will give hours of visual enjoyment and educational insights. As the Sun becomes increasingly more active, you will appreciate that the instrument can grow right along with it. Solar activity changes by the hour or even by the minute - what appears now may grow or may disappear giving you a real insight into the changing nature of our nearest star.
Lunt Solar System are pleased to announce a new addition to their line-up of the Hydrogen-Alpha telescopes - the LS50THa. The telescope is a 50mm, unobstructed, pressure-tuned, dedicated Hydrogen-alpha telescope with a bandpass of <0.75 Angstroms and is fully upgradeable at any time without ever having to go back to the factory. The package provides the basic essentials perfect for a first time introduction to solar observing, while also including the newest technology for fine tuning, allowing basic research of the Sun’s disk and some surface details.
The Lunt LS50THa Solar Telescope comes complete with their highly regarded Pressure Tuner. 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.LS50THa Package Features:
