Lunt 50mm Ha Etalon-Filter-System with B3400 blocking filter for 2" focuser
H-alpha Single Pass Front Mount Etalon System for telescopes with 2" focuser and up to 3060mm focal lentgh.
Introducing the LS50 Hydrogen-alpha system. To kick off the new company we are offering the 50mm aperture (no central obstruction) integrally tuned etalon for use on any customer supplied refractor. System includes the B3400 blocking filter which provides full disk images on telescopes up to 3060mm focal length.
Because the LS50 has an estimated bandpass of <0.75 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 ~<0.55 (dependant upon scope) allowing for higher resolution viewing and/or imaging.
