Tele Vue 1.25" OIII Bandmate Filter

Introducing Televue's all-new Bandmate filters! The Oxygen-III filter features a 1.25" barrel and is designed for planetary nebulae observation. This narrowband filter passes light from doubly ionized oxygen atoms to produce a significant contrast gain even in the most ideal observation settings. This filter makes the difference between observing faint supernova remnants and planetary nebulae and missing them altogether!

All filter materials have been sourced from Germany and tested by Astronomik on a spectrograph to ensure the coating meets design specifications, mechanically tested for fit, cosmetically inspected for digs, sleeks, and pinholes and serialized. The Tele Vue OIII filter is then sent to Tele Vue headquarters to be optically tested in high-power space to ensure no image degradation. This gives you a quality filter of the highest standard created by two of the most respected names in the industry!

Each filter comes with a 10-year warranty against any and all manufacturing defects.
