The LS50THa from Lunt Solar Systems is a 50mm, unobstructed, pressure-tuned, dedicated Hydrogen-alpha telescope with a bandpass of <0.75 Angstroms.
The excitement of viewing our Star through a dedicated solar telescope is sure to provide many many hours of visual enjoyment and educational insights. This package is fully upgradeable at any time without ever having to go back to the factory. As the Sun becomes increasingly more active, you will appreciate that the instrument can grow right along with it.
The Lunt LS50THa Solar Telescope, complete with a Pressure Tuner, 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.
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:
- A Narrow Band Hydrogen-alpha Dedicated System.
- A refractor-based system with a 50 mm front objective.
- An internal Etalon with a pressure tuner allows for <0.75 Angstrom bandpass.
- The system includes the clamshell with threaded holes for mounting and dust caps.
Choose an LS50THa with the blocking filter that is right for you:
B400 – for visual use
B600 – for larger field of view
All Lunt Solar Systems h-alpha telescopes require a Lunt Blocking Filter!
Add the specially-designed LS50C compact double stack filter (sold separately) and lower the bandpass to <0.5 Angstroms for more surface detail. The LS50C threads directly onto the LS50THa for instant gratification!
