Solar Filters System

Product code: LF120 Manufacturer: Lunt Please contact us to confirm the price Single Pass Front Mount Etalon System. LS75 Hydrogen-alpha system - 75mm aperture (no central obstruction) integrally tuned etalon for use on any customer supplied refractor. System includes the B600 blocking filter standard which provides full disk images on telescopes up to 600mm focal length. Larger blocking filters suitable for longer focal length telescopes are also available options. Because the LS75 has an estimated bandpass of <0.75 Angstroms it is capable to providing high contrast views of both surface and edge detail. Adding an additional etalon system will reduce the bandpass to ~<0.55 (dependant upon scope) allowing for higher resolution viewing and/or imaging. The following combinations are available: LS75FHa/B600 mm LS75FHa/B1200 mm LS75FHa/B1800 mm LS75FHa/B3200 mm Double Stack Etalon LS75FHa (Matched)
