Baader Planetarium Highspeed Filter Set
The highspeed filters from Baader are particularly useful in the case of very fast optics like RASA, Boren-Simon Newtonians or telephoto lenses. Traditional narrow band filters suffer from a substantial loss of transmission due the minimal shift of the central wavelength if used with very fast optics. Too little light reaches the sensor.

The highspeed filters from Baader take this shift into account. Thus the best light efficiency is ensured. Additionally, all Baader filters have an efficient anti-reflective coating.
Size:1.25" mounted
Filter thickness:2 mm
Coating:dielectrical coating
Height of the filter cell:6 mm
Filter set Highspeed H-Alpha, O-III, S-II

"Used these for a wide-field shot of the Flaming Star Nebula with M36 and M38, plus a lot of other DSOs with a Sigma 50-100 mm F/1.8 zoom at full aperture. Getting very nice results with little or no halos. Hope to use them on a future Samyang 135mm F/2 or RASA 8 as well"
