Filters and telescopes for solar observation

in white light, calcium-K and H-alpha

These H-alpha filters are designed to upgrade your astronomical telescope for solar observing during the day. Several filter sizes can be matched with an adapter-plate to the existing scope aperture. These systems include the front mounted Etalon filter and the required rear mounted 50.8 mm (2") or 31.7 mm (1.25") blocking filter for the focuser.
