Lunt - 60mm Ha Telescope with Double-Stacked 50mm External Etalon System and B600 with Pressure Tuner & Starlight Instruments 2 " Feather Touch Focuser

Lunt Solar Systems - 60mm Double Stack B600 Solar Telescope w/Pressure Tuner - 2" FeatherTouch Focuser

                                                    Possibly the only Solar Telescope you will ever need !

• Ultra-Narrow Band Hydrogen-alpha (656.28nm) Dedicated System.
• A 60mm refractor based system with additional 50mm aperture secondary removeable filter.
• Dual etalons with the NEW Pressure Tuner allows for <0.5 Angstrom bandpass, providing 3D like enhanced surface detail.
• Use the Lunt double-stacked LS60T in Single-Stack mode for prominence viewing or in Double-Stack mode for surface detail. 
• The larger rear trimming filter allows for imaging with most basic camera equipment.
• The system includes the clamshell with threaded holes for mounting, dust caps, and is delivered in Aluminum reinforced cases.
• An eyepiece is NOT included, and although any eyepiece will work, we recommend the Lunt Zoom.

As Solar Maximum approaches, the addition of a secondary front mounted interference filter and the upgrade of the rear trimming filter, the visual package quickly becomes a superb visually enhanced instrument with the ability to also image the Sun utilizing basic camera equipment. Adding the front filter provides a view of the Sun in virtual 3D.

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 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 thru it’s structure toward you and away from you, allowing for enhanced visual and imaging capability for the observer.  Lunt Solar Systems' Doppler True Pressure Tuning method allows you to rapidly scan the scope’s sub-angstrom passband over the hydrogen alpha wavelength.  Simply put, the advanced technology of Doppler True Tuning for fine adjustment of the center wavelength allows research of the Sun’s disk and surface details at increased image scale. Prominences, flares, super granulation, filaments, and active regions will be precisely observed.

This package includes a B600 (6mm) Blocking Filter (required!) for visual use and imaging applications.
