These packages can be designed for use by beginners thru advanced.

Introducing the LS50 Hydrogen-alpha system. To kick off the company we offered 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 540mm focal length. Larger blocking filters suitable for longer focal length telescopes are also available options.

These Hydrogen-alpha Filters are designed to retrofit (adapters required) the customer supplied telescope for use during the day. They are easily removeable so that the scope can continue to be used for night observing.
Several sizes can be matched to the existing scope aperture. Systems include front mounted filter and the required rear mounted 2″ or 1.25″ blocking diagonal (dependant upon focuser size).

Because the LS50 has an estimated bandpass of <0.70 Angstroms it is capable of providing high contrast views of both surface and edge detail. Adding an additional etalon system will reduce the bandpass to ~<0.50 (dependant upon scope) allowing for higher resolution viewing and/or imaging.
