Bandmate™ NebuStar™ Filter

High-performance, dielectric, squarewave "UHC" type general purpose narrow-band filter great for all nebulae types and instrument sizes.

  • Red blocking allows brighter, sharper star images not plagued with red fringing seen on most filters of this type.
  • Highest transmission in critical bands

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.
