Lunt Solar 100 mm H-Alpha Telescope

The LS100THa from Lunt Solar Systems is a 100 mm dedicated Hydrogen-alpha telescope with a bandpass of <0.7 Angstroms. Pressure tuning is standard on the LS100THA, as is a high precision Starlight Instruments Feather Touch 2" Focuser with 10:1 dual speed focusing controls. You will also receive a Tele Vue Sol-Searcher Sun Finder, a 12" dovetail, and an aluminum carry case for safe storage and transport. Choose your desired blocking filter (1200, 1800, or 3400) from the above drop-down.

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 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 tip, following the filament through its 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.

About Your Drop-Down Choices:

Choose a B1200, B1800, or B3400 Blocking Filter from the drop-down. The B1800 is a worthy upgrade if you will be doing photography through the scope or you want a wider field of view visually. The B3400 gives an even wider field of view than the B1800 and is the perfect choice for those who want to image with a larger imaging sensor. The price of the telescope package will adjust depending on the blocking filter you choose.

Please Note: The 100mm H-Alpha Telescope with B3400 Blocking Filter currently has an Expanded Lead Time.
