  • Tele Vue 3.5" Extension Tube - X3C-0009

    The Televue X3C-0009 is a 3.5" long, 2" diameter extension tube. There are times when it necessary when doing photography to need additional focuser travel through many scopes - particularly when the 2" diagonal is removed.

    Some scopes, such as the Televue TV-101 and Televue TV-102, require both the 2" and 3.5" extension tube (before inserting the camera adapter) in order to achieve proper focus photographically. The Televue 3.5" Extension Tube can also be used in any 2" focuser when additional focuser travel is needed to bring an eyepiece to focus, too!

    Televue Product Number: X3C-0009

    Extension to focus

    With the 3.5 Televue extension, one can eliminate the diagonals for a Williams Optics 132/f7 and the Antares 4 inch f13 refractors. A 2.6 inch ( effective 2 inch )does not. For planatery views, straight on visual viewing is still a most pleasant viewing experience alternative. Have not tried with a Binoviewer as yet.
