Details
- 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 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
Product Series
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.
