Narrowband (NB) filters  enhance contrast of emission objects by accepting only a narrow range of wavelengths around the emission lines of hydrogen (H-a, 656 nm), oxygen (OIII, 501 nm), sulfur (SII, 672nm) and others.

Astrodon is also providing its latest Generation 2 E-Series 1.25" filters mounted in 31 mm inserts specifically for the popular QSI CCD cameras, such as the QSI532 and QSI583.  

Astrodon Tru-Balance RGB filters have revolutionized CCD imaging. Their popularity is due to ease-of-use, high optical throughput and great resulting color for galaxies, star clusters and nebulae.
