Flip mirror for ccd use.. placement and focusing.
This flip mirror has M42 thread (male) on one side so you can
screw on various CCDs (like the Starlight Xpress models, tight fit,
but works) and 1.25" nose on the other side, to slip right into your
focuser. Another 1.25" on top for the eyepiece. Plastic, lightweight,
and very small so very favorable for focus-travel issues. Asking
only $49.00 + $6 shipping OR BEST OFFER OR BEST TRADE.
