100mm H-alpha Single Pass Front Mount Etalon System for telescopes with 2” focuser and up to 540mm focal length.

Introducing the Lunt LS100FHa Hydrogen-alpha system. We are offering the 100mm aperture integrally tuned etalon for use on any customer supplied refractor. System includes the B600 standard for use on telescopes up to 540mm focal length. Blocking filter required.

Because the LS100FHa has an estimated bandpass of <0.7 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 ~<0.5 (dependant upon scope) allowing for higher resolution viewing or imaging.

Delivered with order:
• Main Filter
• Blocking Filter (for 2” focuser)
• Transport case
