Home Telescopes Lunt Solar Telescopes Lunt LS50THa/B400PT H-alpha Solar Telescope
The LS50THa solar telescope offers 50 mm free aperture, 350 mm focal length with a bandwidth of <0.75 Angstrom for full H-Alpha views of the Sun. The telescope is fitted as standard with a ergonomic air-pressure tuning system the "Pressure-Tuner", the adjustable Etalon is safely installed inside the telescope. Solar detail can be easily viewed through the Lunt LS50THa and swept through frequency ranges with the hand-operated pressure tuner in order to view surface detail - granulation, sunspots and filaments, as well as solar atmospherics - flares, loops and prominences. This highly portable system is an ideal travel companion for wherever you go and will easily fit on most commercially available camera tripods, via a standard 1/4" whitworth thread. Dovetails can also be bought as an additional extra in order to mount this solar scope on Vixen/Skywatcher compatible mounts and those that take the wider Losmandy system as well.A B400 blocking filter is installed inside the star diagonal. The B400 is really good for visual observing. For solar imaging we advise the version LS50THa/B600PT with larger blocking filter. Focusing is achieved by a smooth, non-rotating Helical focuser.Double-stacking the Lunt LS50THa, producing a bandwidth of only <0.5 Angstrom is possible by using the additional available LS50C filter (0550210). This filter threads directly onto the front lens cell of the LS50THa telescope.Specifications:Aperture: 50 mmFocal Length: 350 mmBandwidth: <0.75 AngstromTuning: air-pressure tuning system "Pressure-Tuner"Blocking Filter: B400non-rotating Helical focuserTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)
