Alpine Astronomical Baader 2-to-1.25″ Reducer For NT Steeltrack Focusers(Alpine Astronomical Baader 2 To 1 25 Reducer For Nt Steeltrack Focusers)

Designed for the Newtonian model of their NT Steeltrack focuser, the Alpine Astronomical Baader 2-to-1.25″ Reducer allows you to use the smaller and more common 1.25″ size eyepieces and accessories in the focuser’s larger 2″ holder. This conventional holder has an easy-to-use thumbscrew that tightens against a brass compression ring so it won’t mark or mar the eyepiece’s nosepiece. The reducer has a short 4.5mm optical height to minimize its effect on the back-focus distance, and has internal threads for installing 2″ eyepiece filters.
