SBIG 50 mm square optical filters are compatible with FW7-STX filter wheels, which work with STX-16803 and Aluma AC4040 cameras. These filters are built for SBIG to our exacting specifications. All filters are parfocal, which avoids unnecessary refocusing.
Filters and filter sets 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
- Hydrogen Beta (Hb) – 486.1 nm, bandwidth 8.5 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)
Clear passes all wavelengths but is parfocal with the other filters.
