Lunt 100mm Ha Etalon-Filter-System with B1800 blocking filter for 2" focuser

H-alpha Single Pass Front Mount Etalon System for telescopes with 2" focuser and up to 1620mm 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 B1800 for use on telescopes up to 1620mm 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 and/or imaging.

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