TeleVue - OIII Bandmate Filter 1 1/4 inch

Bandmate™ filters yield bright, sharp and contrasty images - even in the optically sensitive position in front of the
diagonal. Optical glass and red filtering allows for sharp and bright views of nebulae with embedded star clusters - such as the
Lagoon Nebula (M8).
Bandmate™ OIII Filter
This OIII filter particularly enhances planetary nebulae in larger telescopes.

    * Narrowband filter for high transmission, with high blocking of unwanted longer wavelengths to yield high-contrast images.
    * Ion beam technology and optical glass produces low scatter in a hard stable coating to reduce changes due to temperature
and humidity.
    * Optical quality ground and polished BK7 glass yields sharp star images - even when filter is placed in front of diagonal.

100% quality control:

    * Every single filter is checked optically and cosmetically to assure performance.
    * Every filter is individually serialized. 

Features of TeleVue Bandmate™ Filters

    * Optical grade BK7 glass to insure no image degradation due to the substrate.
    * Ion beam deposition of the coatings produces hard, stable coatings to reduce changes due to temperature and humidity.
    * Dielectric filter for high transmission and blocking of unwanted wavelengths provide high contrast images.
    * Aluminum filter cells precision machined and laser etched.
