Filters LS 100F Ha H-Alpha filter set for 1800mm focal length

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

Introducing the LS100 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 LS100 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.
