Product information "LUNT LS50FHa/B1800d2 H-alpha solar filter"
50mm H-alpha solar filter system with B1800 blocking filter, for front mounting at telescopes with 2" focuser, and up to 1620mm focal length.
The LS50FHa H-alpha Etalon filter system with 50mm aperture (no central obstruction) for use on any refractor and many other telescopes. Because the LS50FHa has an estimated bandwidth of <0.75 Angstrom it is capable to providing high contrast views of both solar surface and edge detail (prominences).
The system includes the B1800 blocking filter, which is usable for telescopes up to 1620mm focal length. Larger blocking filters suitable for longer focal length are also optional available. The blocking filter is installed in a 90° star diagonal for 2" focuser. This diagonal is equipped with a reception for 1.25" eyepieces and a T2 camera connection.
Adding an additional available double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom.

Because the LS60FHa has an estimated bandwidth of <0.75 Angstrom it is capable to providing high contrast views of both solar surface and edge detail (prominences).The system includes the B600 blocking filter, which is usable for telescopes up to 540mm focal length. Larger blocking filters suitable for longer focal length are also optional available. The blocking filter is installed in a 90° star diagonal for 1.25" focuser. This diagonal is equipped with a reception for 1.25" eyepieces and a T2 camera connection.Adding an additional available double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom.FEATURESAperture: 60 mmNo central obstructionBandwidth: <0.75 AngstromTuning: tiltable EtalonHousing diameter: 95 mmLength: 85 mmWeight: 0.85 kgFront thread: M90x1 female threadRear thread: M90x1 male threadBlocking filter: B600 in diagonal for 1.25" focuserMaximum focal length of telescope: 540 mmSCOPE OF DELIVERYLS60FHa solar filterB600 Blocking Filter (for 1.25" focuser) in star-diagonalTransport caseInstruction manual

LUNT LS40FHa H-alpha double-stack filter for LS40THa
€998.00*
Double-stack filter for LS40THa telescopes.
The bandwidth of H-alpha systems can be reduced by so-called "double-stacking". A smaller bandwidth provides much more contrast at the solar surface, thereby many more details will become visible.
Double-stacking with a bandwidth of only <0.55 Angstrom is also possible at the LS40THa telescopes. Therefore Lunt Solar Systems has especially designed this LS40FHa double-stack filter in compact housing.
FEATURES
Aperture: 40 mm
Bandwidth: <0.55 Angstrom
Tuning: mechanical tilt-tuning
Housing diameter: 70mm
Length: 60mm
Weight: 0,3kg
only usable together with a LS40THa telescope!
