The amazing Lunt Solar Systems LS152THa is a Refractor based, dedicated Solar Telescope featuring a precision aligned doublet lens with advanced high contrast coatings, a 152mm Optical Objective, 900mm focal length, and f/6 focal ratio.  The LS152 boasts  the largest and highest resolution image size of any single etalon dedicated scope providing a perfect balance of resolution and performance perfect for the Intermediate to Advanced User. A 100% unobstructed system it is equally impressive at both high and low magnifications.

Utilizing both advanced hi-contrast coatings and the new Doppler True Pressure Tuning system, the user will be able to experience crisp, sharp, high magnification visual images, as well as utillize this system for high end digital processes. True Doppler 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 location 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 very tip, following the filament through its' structure toward and away from you, allowing for enhanced visual and imaging capability for the observer. 

The Internal Etalon with True Doppler Pressure Tuning provides  a <0.65 Angstrom bandpass centered on 656.28nm - the prime Hydrogen-alpha wavelength.  The LS 152 offers another huge advantage in that the internal Etalon is fully interchangeable with an optional Calcium-K module (CaK) which has internal Narrow-band filters which allows a <2.4 Angstrom bandpass which then gives the LS152 multiple wavelength functionality.  Want more?  The LS152 can also be converted for nightime viewing with an  (Optional) special backing plate & focuser kit  #LS152T/BP&F.

Completing this awesome package  are the Included silky smooth Starlight Instruments FeatherTouch dual speed focuser with 10:ratio, a Lunt Zoom Eyepiece,  dust capsmounting rings, dovetail bar,  a Lunt B1800 (18mm) Blocking Filter Diagonal, and a high quality Aluminum carry case.

 * BLOCKING FILTERS are REQUIRED on all Lunt Solar Systems *

 Lunt Solar Systems currently offers 4 blocking filter apertures for use with our Etalon systems. The Blocking Filter houses additional filters which are required for the safety and performance of the solar package.  Lunt Solar blocking filters contain a unique filter system. Lunt will only warranty safety or performance when a Lunt blocking filter is paired with a Lunt H-alpha filter or telescope.
