50mm Round Optical Filters

SBIG 50mm round optical filters are compatible with FW8S-STXL filter wheels. Also work with the older self-guided STXL filter wheels.
詳細介紹
These filters are built for SBIG to our exacting specifications. All filters are parfocal, which avoids unnecessary refocusing. They are typically 3mm thick, and 50.8mm in diameter.


 

Filters and filter set available include:

  • Luminance (L)
  • Red (R)
  • Green (G)
  • Blue (B)
  • Clear (C)
  • Hydrogen Alpha (Ha) – 656.3 nm, bandwidth 6.5 nm
  • Sulphur II (SII) – 672.4 nm, bandwidth 6.5 nm
  • Oxygen III (OIII) – 500.7 nm, bandwidth 6.5 nm
  • LRGB Color Imaging Package (four filters)
  • Narrowband Package – Ha, SII, OIII (three filters)
  • Deep Sky Package – L, R, G, B, Ha, SII, OIII (seven filters)
