CCD Filter for Astrophotography

Filters for Astrophotography

With modern interference filters, amateur astronomers can now achieve excellent image results. The applications include narrow-band emission line filters, broader-band color filters and filters for suppressing artificial light emission.

This is the filter for imaging in moonlight or light pollution with a colour CMOS camera - or even in dark-sky conditions if you want total isolation and control over your channels, narrowband-style.

Altair DualBand 6nm Filter Features:

  • Capture the two main emission nebulae bands at the same time, whilst suppressing light pollution, moonlight, and airglow.
  • Acquire more data in less time, opening up your imaging window, even into the summer months when it isn't quite dark.
  • If you have the 6nm Ha/Sii Ultra filter and the Sii/Ha version, you can capture twice the Oiii data in each imaging session and combine them for true SHO Hubble style imaging with a colour camera!
  • Extremely steep bandpass yields maximum contrast in extreme light pollution: 6nm FHWM centred on 500.7nm Oiii wavelength, and 5.5nm FHWM centred on the 656.28nm Ha wavelength.
  • No halos. We have not had any reports of halos caused by this filter in testing, and we don't expect any with our new V2 hard coating technology.

Altair Astro Premium 1.25" CLS-CCD Filter features:
  • Multi-Layer Anti-Reflection coating to reduce star-halos and reflections from camera optical window.
  • Batch-tested for consistency.
  • Ultra-flat glass by Schott Germany. 1.85mm Glass 30sec parallel, optical polish to MIL Spec. MIL-O-13830.
  • High quality dichroic/dielectric coatings. Electron-beam gun evaporation with Ion-assisted deposition coating technology for durability and resistance to scratching, as well as stability on CWL (central wavelength). No deviation affected by temperature change.
  • UV/IR block for imaging - star bloat reduction with refractors.
  • Precision CNC machined filter cell for strain-free mounting and freedom from tilt.

Altair Quad-Band 2" Filter for OSC CMOS, CCD and Modified or Unmodded DSLR cameras.

This is the new QuadBand V2 Coating technology which includes:

  • Halo suppression. We have not had any reports of halos caused by this filter in testing.
  • Increased blocking of UV, IR and unwanted visual range wavelengths. UV OD7 (T0.00001%) Visual OD5 (T0.001%) and IR OD4 (T0.01%) for the ultimate in skyglow blocking.
  • Higher transmission % of desired wavelengths Ttop 95% (Average 5% higher transmission of desired wavelengths).
  • Ha and Oiii wavelengths at 35nm FWHM for with less tail-off to reduce unwanted light pollution.
