[Tinderboxsky (Steve)]

Baader 2” Semi APO filter in very good, original condition. Glass is clear and unmarked. No longer required as I have moved to EAA only observing.

Worked as advertised in my Vixen NA140SS achromat. They are more effective for visual observing in larger aperture achromats. The lowered light through put makes them less useful for small apertures.

$80 including postage.

Please PM me if interested or would like more information.

Thanks
Steve.
