Lunt Solar Systems' Solar Filter Kit gives users an objective lens hydrogen-alpha filter and a 34mm blocking eyepiece filter for observing the Sun's surface and edge. The Ha filter attaches to the front objective of a user-supplied 100mm refractor telescope to provide unobstructed <0.70 Angstrom filtration. It mounts to the front of the optical tube assembly (OTA) using a telescope-specific adapter that is sold separately. This filter must be used with the eyepiece blocking filter, and another HA filter may be threaded on it to double-stack for a <0.5 Angstrom bandpass. It comes with an aluminum foam-lined hard carrying case for safe and secure transportation and storage. The 34mm aperture blocking eyepiece filter is recommended for use on optical tube assemblies (OTAs) with a focal length of up to 3400mm for visual observation or 1800mm for astro-imaging. The straight-view viewing configuration filter fits into 2" focusers, and accepts any user-supplied 1.25" eyepieces and accessories.

  • 100mm Hydrogen-Alpha Solar Filter

    Lunt Solar Systems' 100mm Hydrogen-Alpha Etalon Solar Filter attaches to the front objective of a user-supplied refractor telescope to provide non-obstructed <0.70 Angstrom filtration for observing the Sun's surface and edge. This filter must be used with an eyepiece blocking filter and is offered here to those who already have one, or wish to use it for double-stacking with another HA filter for a <0.5 Angstrom bandpass. It mounts to the front of the optical tube assembly (OTA) using a telescope-specific adapter that is sold separately, or simply screws onto the threads of another Lunt 100mm HA filter for double-stacking. The filter comes with an aluminum foam-lined hard carrying case for safe and secure transportation and storage.

  • 34mm Blocking Eyepiece Filter (2" Straight Tube)

This model is recommended for use with optical tube assemblies (OTAs) with a focal length of up to 3400mm for visual observation or 1800mm for astro-imaging.
