Lunt H-alpha Telescope LS230THa/B3400/PT


 

The LS230THa/PT (pressure tuned) is a complete and dedicated Hydrogen-alpha Solar Telescope with an Image Scale of 3,366

Soon to become the largest aperture Solar Telescope currently available, the LS230THa/PT will provide the highest level of performance ever produced in a Solar Scope.

A precision aligned refractor with a fully un-obstructed 230mm Aperture. The 100% unobstructed system will perform to the highest level at both low and high magnifications. Utilizing advanced hi-contrast coatings and the new Doppler True Pressure Tuning system the user will be able to experience an un-paralleled level of visual and imaging performance.
The system is designed as a dedicated Hydrogen-alpha telescope. Unlike its smaller LS152THa the system is not modular.
