Product Description

LUNT SOLAR SYSTEMS - B600 (6mm) Blocking Filter 2" - in Extension Tube with T2 and 2” connection

 

  • B600 for Visual Use up to 600mm Focal Length Telescope
  • B600 for Imaging Use up to 400mm Focal Length Telescope
  • The Lunt Solar Systems B600 Blocking Filter provides a full solar disc image only when used with a Lunt Solar Systems H-Alpha Etalon Filter
  • A Blocking Filter is absolutely required  for the safety and performance of telescopes when Solar Observing

 

NOTE:   Image above shows 1.25" model for illustration purposes

 When Imaging with a Lunt Solar System it is recommended that the user opt for the next larger Blocking Filter than that recommended for Visual use.This is due to the fact that most Imaging Systems require additional “backfocus”. This requires that the Blocking Filter be moved further up the light cone. As a result the aperture of the Blocking filter needs to be larger to allow for the larger cone size.

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.
