Withdrawn: UHC Filter (1.25")

Orbinar 1.25” UHC Filter (#1039) $40
For observation and photography of emission/reflection nebulae from light polluted skies. Filters out scattered light generated from common artificial sources (mercury vapour & sodium vapour street lamps, neon lights), but passes relevant wave lengths for nebulae observations (H-Beta 486nm, O-III-Lines 496nm and 501nm, H-Alpha-Lines 656nm).

Filter works well, noticably improving nebula contrast from suburban skies. Selling because I now spend much more time with 2" Astrophotography than visual, and need to fund more stuff!!!

(shifted from Eyepieces forum "Odds & Ends" thread)

Please send a PM if interested.

Cheers,
Jeff
