Recommended Posts

  • ALTAIR

Hi there, we've developed a new Altair Dual-Band 7nm filter for extreme light pollution

 

- 6.5nm Oiii, 7nm Oii FHWM very steep bandpass for excellent contrast

- OD4 99.9% blocking of unwanted wavelengths

- Flat top profile for fast focal ratios

- Complements Altair TriBand and QuadBand filters for those with severe light pollution

- Easily image from central London Bortle 8, check out customer examples in the Altair Facebook group
