SFE-M75-040

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.
