Lunt H-alpha Solar Filters
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.
Provides much more contrast at the solar surface, thereby many more details will become visible
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.
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.
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.
