These H-alpha Filters are designed to retrofit your astronomical telescope for observing the sun during the day. Several filter sizes can be matched with an adapter-plate to the existing scope aperture. Systems include front mounted Etalon filter and the required rear mounted 50.8 mm (2") or 31.7 mm (1.25") blocking filter.
H-alpha filter systems with 100mm aperture and <0.7 Angstrom bandpass. Adding an additional available Double-Stack etalon system will reduce the bandpass to <0.5 Angstroms. These big filters will show many details of the sun to the advanced solar observer.
H-alpha filter systems with 60mm aperture and <0.7 Angstrom bandwidth. Adding an additional available Double-Stack etalon system will reduce the bandwidth to <0.5 Angstroms. These 60mm filters can be combined with the 60mm H-alpha telescopes for double stacking.
DSII module for all Lunt Solar Systems telescopes with 80 mm aperture. Internal double stack filter with air-pressure tuning system. Reduces the bandwidth to <0.5 Angstrom!
H-alpha filter systems with 50mm aperture and <0.75 Angstrom bandpass. Adding an additional available Double-Stack etalon system will reduce the bandpass to <0.55 Angstroms. The 50mm filter system provides very good results in viewing and imaging the Sun.
