Lunt 60mm True Tuned Double Stacked Solar Telescope with B1200 Filter and 2" Crayford Focuser

$3,557.40

The addition of a secondary front-mounted interference filter and the upgrade of the rear trimming filter transforms the Lunt LS60THa into 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. An active ball of churning boiling gasses that spew from the surface in what can be violent eruptions. Cause and effect can be viewed and imaged in real time.

An upgrade to the visual system, which comes standard with the pressure tuning system, puts a research grade instrument into the hands of the observer and the imager.

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 thru 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. Probably the only Solar Telescope you will ever need.

Choice of filter:
B600 – for visual use
B1200 – for larger field of view and imaging with standard cameras
