The ZWO LRGB 36mm unmounted filters have better transmission, better coating, better color separation.
The RGB color combine weights will be approximately 1:1:1
- Fine-optically polished to ensure accurate 1/4 wavefront
- More than 92% transmission at passband
- Infrared wavelength 700-1100nm cut-off
- Precision off-band blocking
- Multi-layers anti-reflection coating
- Small spectral gap to minimize effect of light pollution
- More parfocal thickness 2mm
