Details

Lunt  -  Blocking Filter B1200  2" -  in Star Diagonal with T2 connection


Lunt Solar Systems B1200 Blocking Filter - 1.25" - Star Diagonal

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

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

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

 

Focal Length Specifications (VISUAL USE):

• B600 for Visual Use up to 600mm Focal Length Telescope

• B1200 for Visual Use up to 1200mm Focal Length Telescope

• B1800 for Visual Use up to 1800mm Focal Length Telescope

• B3400 (straight thru only) for Visual Use up to 3400mm Focal Length Telescope

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.

Focal Length Specifications (IMAGING USE):

• B600 for Imaging Use up to 400mm Focal Length Telescope

• B1200 for Imaging Use up to 600mm Focal Length Telescope

• B1800 for Imaging Use up to 1200mm Focal Length Telescope

• B3400 (straight thru only) for Imaging Use up to 1800mm Focal Length Telescope

 

 

Product Series

For telescopes with 2 inch eyepiece-holder 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. We are currently offering the B600, B1200 and B1800 in a T2-M42 x 0.75 diagonal format with fixed filter. The B1800 and B3200 is also being offered in a 2 inch straight thru with a tiltable filter mechanism. The B600 is for maximum focal length 540mm, B1200 is for 1080mm, B1800 is for 1620mm and the B3200 is for 2880 mm maximum focal length. This is the 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. Lnt can only warranty safety or performance when blocking filter is paired with a Lunt Solar System. Options • The T2-M42 x 0.75 diagonal series will be available in a straight thru option later in the year. There is currently no introductory date set.
