Product Description

LUNT SOLAR SYSTEMS -  B3400 Blocking Filter  in extension tube with T2 and 2″ connection

The Lunt Solar Systems B3400 Blocking Filter is its own unique system unique located in a 2" straight through housing with a tiltable filter mechanism. The blocking filter is required element for the safety and performance of any solar package - including Lunt H-Alpha parts. The Lunt Solar Systems B3400 filter will provide a full disk image of the Sun with telescopes that have a maximum of 3400mm of focal length.

Choose your blocking filter carefully for your telescope's focal length. If you were to use a larger blocking filter than is necessary to achieve a full disk image on your telescope system, the result may show image "ghosts" at the edge of the field of view.  For best performance, be sure to pair your Lunt Solar Systems h-Alpha filter with the proper sized Lunt blocking filter.

Because Lunt Solar Systems blocking filters contain a unique filter system. Lunt will only warranty the safety and/or performance of their systems when a Lunt blocking filter is paired with a Lunt Solar Systems Etalon system.

  • The Lunt Solar Systems B3400 Blocking Filter provides a full solar disc image when used with a Lunt Solar Systems H-Alpha Filter on telescopes with a maximum focal length of 3400mm.

  • The Blocking Filter is a necessary component for safety and performance in all solar telescopes.

  • This unique Lunt Solar Systems B3400 Blocking Filter design is located in a 2" extension tube housing that has a T2 and 2" connection.

  • Must be used in conjunction with a front etalon.
