Product information "LUNT LS50FHa/B1200d2 H-alpha solar filter"
50mm H-alpha solar filter system with B1200 blocking filter, for front mounting at telescopes with 2" focuser, and up to 1080mm 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 B1200 blocking filter, which is usable for telescopes up to 1080mm 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 LS100FHa has an estimated bandwidth of <0.7 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 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 ~<0.5 Angstrom.FEATURESAperture: 100 mmBandwidth: <0.7 AngstromTuning: tiltable EtalonHousing diameter: 162 mmLength: 101 mmWeight: 2.75 kgFront thread: M120x1.5 female threadRear thread: M120x1.5 male threadBlocking filter: B600 in diagonal for 2" focuserMaximum focal length of telescope: 540 mmSCOPE OF DELIVERYLS100FHa solar filterB600 Blocking Filter (for 2" focuser) in star-diagonalTransport caseInstruction manual

LUNT LS60MT/B600R&P Multipurpose ED Telescope for Sun + Night-Sky
Modular designed multipurpose telescope, both for observing the sun in the H-alpha wavelength, as well as for night sky observations. Easy conversion between the different applications with a few simple steps. Excellent image quality due to 2-lens ED optics with 70mm aperture for night sky observation, and 60mm usable aperture for H-alpha solar observation.With innovative air pressure tuning system, high-quality 2 inch (50.8mm) Rack&Pinion (R&P) focuser, and B600 blocking filter.Solar observing in H-alpha:The LS60MT/B600 is a complete telescope for observing the sun in H-alpha light, with 60mm free aperture (no central obstruction) and 420mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An internal Etalon filter achieves a bandwidth of <0.7 Angstrom with the innovative air pressure tuning system Pressure-Tuner. Tuning is done by slightly changing the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, making it easy to tune to the H-alpha line. The pressure tuner guarantees a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A set of collimating lenses installed in the telescope ensures best performance.Fine adjustment is achieved with a solid 2 inch Rack&Pinion focuser with 10:1 reduction.Blocking-filter is the B600. The B600 is good for visual solar observing. Also solar imaging is possible by cameras with small CCD chip. We recommend a LS60MT with B1200 blocking-filter by using cameras with middle or large sized CCD chips.The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepieces and with a T2 camera connection.Observing the starry night sky:The H-alpha Etalon system can be removed from the telescope in a few easy steps thanks to its modular design. The 2-lens ED refractor can then be used as a normal telescope with 70mm aperture and 420mm focal length for observation and photography of the night sky. The ED Doublet lens will offer an excellent image. It can be used with a standard 2 inch zenith mirror at the R&P focuser.With an additional Amici prism, the telescope can of course also be used during the day for nature and landscape observations.This makes the LS60MT, with its small dimensions and low weight, also an ideal travel telescope for all applications!More applications:With additionally available accessories the LS60MT offers even more possibilities!- Double-StackThe LS60MT telescope can optionally be upgraded with the additionally available double-stack filters LS50FHa or LS60FHa (part numbers 0550200 and 0550250). These filters will be simply screwed on the front of the LS60MT, no additional adapters are necessary. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Therefore much more details on the solar surface will become visible.- Solar observing in White-LightIf the H-alpha unit has been removed, of course either a sun filter to be installed in front of the objective, or a Herschel-wedge at the focuser can be used to observe the sunspots in White-Light.- Solar observing in Ca-K wavelengthCertainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS60MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.This makes the LS60MT a completely universal usable telescope!FEATURES2-lens ED refractor, FPL-51Aperture: 70mmUsable aperture in H-alpha: 60mm (no central obstruction)Focal length: 420mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerBlocking filter: B600 with 1.25 inch and T2 connectionFocuser: Rack&Pinion focuser with 10:1 reductionTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)Weight with H-alpha unit: 3.8kgWeight without H-alpha unit: 2.6kgLength with H-alpha unit and blocking filter: 40cmLength without H-alpha unit: 31cmSCOPE OF DELIVERYLS60MT Multipurpose TelescopePressure-TunerB600 blocking filter in star-diagonal housing2 inch Rack&Pinion focuserTube ring with 1/4-20 connection for mounting on photo-tripodsTransport case (53x33x17cm)Instruction manual
