Lunt - Blocking Filter B600 in 2" Diagonal with T2 Connection

Details

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.

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.
