Product Description


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.

Refer to the following Table for correct BLOCKING FILTER Model to use for VISUAL / IMAGING purposes. Selected model (B600) in BOLD
