Lunt Solar Systems - 50mm Ha Etalon Filter PREORDER NOW!!!

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.

allowing for higher resolution viewing and/or imaging.
