Tele Vue Bandmate Hydrogen-beta Filter (2 )
Designed and produced in partnership with Astronomik of Germany with the tight tolerances and exacting standards that both companies are known for, the 2 Tele Vue Bandmate H-beta Filter passes just the aqua-colored hydrogen-beta emission lines found in the Horsehead, California, and other hydrogen-emitting nebulae. The filter bandpass is centered on the 485nm wavelength with a greater than 95% throughput transmission. It is effective for viewing objects that take up the entire field of view-even when using Tele Vue s wide-angle eyepieces. This version of the H-beta filter is set in a 2 aluminum ring to enable its use with larger eyepieces and accessories.
