    Product Description

    Threaded M75 extension tube. Adds 40 mm of extension. Use this with the newer Stellarvue SVX 140 refractor that comes with the Feather Touch 3.5" focuser when used visually so the focuser does not have to be racked out as far.

      SFE-M75-040 threaded extension (adds about 1.5")

      Posted by Jim Mosquera on 11th Mar 2025

      I am using this for (1) visual observation when attached to my 2025 SVX102T-RA scope, using a FeatherTouch (FT) focuser, to bring images to proper focus in my SV 2" mirror diagonal, and (2) in my 2023 SVX90T scope to preclude interference between my eyepieces and an installed PiFinder (plate solving computer) installed on my FT focuser. Threaded extension is installed between the 3" FT visual back and the 3" to 2" reducer in which the focuser resides. Easy installation and works well.
