Beschreibung
Dieser Filter blockiert selektiv die Wellenlängen des Lichts von Lichtverschmutzungsquellen wie Straßenlaternen, nicht aber breite Bereiche des Spektrums.

- Enhance your 8” Rowe-Ackermann Schmidt Astrograph (RASA) by blocking light pollution, improving image contrast, and darkening the sky background.
- This filter selectively blocks wavelengths of light from sources of light pollution, such as streetlights, not broad regions of the spectrum.
- Does not block wavelengths associated with emission nebulae, keeping your nebula images bright and detailed.
- Fits into the 8” RASA’s integrated filter mount, maintaining peak optical performance.
- Optically flat surfaces free of defects, constructed of Schott glass with anti-reflection coatings.
