This terrific German lens is a great fit for CCD imaging (~ 75 mm front element). The quality of Schneider optics is legendary.
The 80mm to 240mm focal length is a good fit for a wide range of CCD imaging projects. f-4 means (of course) a short exposure time! The lens is in great condition, no scratches on the optics & cosmetically very, very good.
This lens is equipped with the standard (threaded) Pentax mount (aka: M42 – 42mm x 1). Starlight MX CCD cameras, and others, use this thread. If you are using T2 as your mounting thread, Pentax to T-2 adaptors are available though photography shops, etc.
I am asking $150; buyer pays actual shipping (your choice)
