Tele Vue Bandmate Oxygen-III Filter (1.25 )
Designed and produced in partnership with Astronomik of Germany with the tight tolerances and exacting standards that both companies are known for, the 1.25 Tele Vue Bandmate Oxygen-III Filter passes light from doubly ionized oxygen atoms. As such, it is great for viewing planetary nebulae and supernovae remnants. The filter bandpass is centered on the 500nm wavelength with a greater than 96% 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 O-III filter is set in a 1.25 aluminum ring to enable its use with standard eyepieces and accessories.
