Product information "LUNT LS40FHa H-alpha double-stack filter for LS40THa"
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.

LUNT LS40THa/B500 H-alpha solar telescope
£1,398.00*
Solar observation in H-Alpha: prominences, filaments, flares ... the most spectacular way to see the Sun - easy and affordable with the LS40THa.Complete H-alpha solar telescope with 40mm aperture, <0.7 Angstrom bandwidth, B500 blocking-filter, and Helical focuser.The LS40THa/B500 is a complete telescope for observing the sun in H-alpha, with 40mm aperture (no central obstruction) and 400mm 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 Etalon with mechanical tilt-tuning provides <0.7 Angstrom bandwidth.Fine adjustment is achieved with a 1.25 inch Helical focuser. Blocking-filter is the B500, this is good for visual observation of the sun. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepiece connection.The easy handling makes this telescope ideal for starting H-Alpha solar observation. Due to its compact dimensions it is also a good travel telescope for the experienced solar observers.The LS40THa telescopes are available with choice of B500, B600 or B1200 blocking filters. The larger blocking filters provide less edge obstruction and a larger field of view for visual observation and photography. Please note that these telescopes have only a very small back focus and therefore photography is difficult. We recommend special astro cameras for photography, which have a very short distance to the sensor, such as the BRESSER Full HD camera item number 4959050.FEATURESAperture: 40mm (no central obstruction, 2-lens refractor)Focal length: 400mmBandwidth: <0.7 AngstromTuning: mechanical tilt-tuningBlocking filter: B500 with 1.25 inch connectionFocuser: Helical focuserDovetail bar at standard GP-level1/4-20 tapped base (standard thread for photo-tripods)Sol-Searcher includedWeight: 1.2kgLength: 41cmSCOPE OF DELIVERYLS40THa Solar TelescopeB500 blocking filter in star-diagonal housing1.25 inch Helical focuserDovetail bar (GP level)Sol-SearcherInstruction manual
