TeleVue Bandmate™ OIII Filter 2"
This OIII filter particularly enhances planetary nebulae in larger telescopes.
- Narrowband filter for high transmission, with high blocking of unwanted longer wavelength 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.
