Celestron Nebula Filter for Celestron Origin

This nebula filter is designed for the Celestron Origin Intelligent Home Observatory. It blocks light pollution and darkens the sky, allowing for clearer views of nebulae even in urban areas. The filter fits into the Origin's integrated filter drawer and transmits key wavelengths including 486nm, 496nm/501nm, and 656nm while blocking much of the rest of the visible spectrum. It is suitable for imaging objects such as the North America Nebula, Lagoon Nebula, Orion Nebula, and Carina Nebula. The filter includes Schott B270 glass with antireflective coating and a foam-lined case.
