Bandmate™ OIII Filter 1.25inch
This OIII filter particularly enhances planetary nebulae in larger
- 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
- Every filter is individually serialized.
