Single Pass Front Mount Etalon System

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 B600 blocking filter standard which provides full disk images on telescopes up to 600mm focal length. Larger blocking filters suitable for longer focal length telescopes are also available options.

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. 

The following combbinations are available:

LS50FHa/B600 mm

LS50FHa/B1200 mm  

LS50FHa/B1800 mm

LS50FHa/B3200 mm
