Lunt Solar Systems - 18mm Blocking Filter PREORDER NOW!!!

Lunt Solar Systems currently offers 4 blocking filter apertures for use with our Etalon systems.

The Blocking Filter houses additional filters which are required for the safety and performance
of the solar package.

Blocking filter required on all Solar Systems
Lunt is currently offering the B600, B1200, and B1800 in a 1.25” diagonal format with fixed
filter.  The B3200 is being offered in a 2” straight thru with a tiltable filter mechanism.

The number after the ”B” refers to the maximum focal length of telescope for which that
particular blocking filter will provide a full disk image of the Sun. A blocking filter larger
than that required to achieve the full disk image may result in image ”ghosts” at the edge of the
field of view.

Lunt Solar blocking filters contain a unique filter system. Lunt can only warranty safety or
performance when blocking filter is paired with a Lunt Solar System.

	

18mm Blocking Filter to be used on telescopes up to 1800mm focal length. B1800 must be used with a
Lunt Solar System front etalon filter.
