Introducing the LS50 Hydrogen-alpha system..... To kick off the new company Lunt is offering the 50mm aperture (no central obstruction) integrally tuned etalon for use on any customer supplied refractor. System includes the B600 standard for use on telescopes up to 600mm focal length. *Blocking filter required.

 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. Specifications: • Aperture: 50mm • Focal Length: Customer Supplied Scope • Band Pass: <0.75 Angstroms RMS • Color: Pearl White with Black Anodize System Includes: • LS50 Ha Filter. • B600 Blocking Filter (Other sized available by request) • Re-enforced case with foam.
