The LS60 Hydrogen-alpha filter system with 60 mm aperture integrally tuned etalon for use on any refractor and many other telescopes.

Because the LS60FHa has an estimated bandwidth of <0.7 Ångström, it is capable to providing high contrast views of both surface and edge detail.

The system includes the B1800 blocking filter, which is usable for telescopes up to 1800 mm focal length. Larger blocking filters suitable for longer focal length are also optional available. The blocking filter is installed in a 90° star diagonal for 2" focuser. This diagonal is equipped with a reception for 1.25" eyepieces and a T2 camera connection.

Adding an optional double-stack etalon system will reduce the bandwidth to <0.5 Ångström and therefore enhance contrast significantly.

On request, you can this system with a blocking filter in a star diagonal for 1.25" focusers. Please contact us for more information.

Important hint: In humid air, blocking filters might tarnish, so keep yours dry. You can get little packages of silica gel for reducing humidity even more. Put one and the filter into a small freezer bag and seal it.
