Baader Green CCD 2" Telescope Filter with LPFC

Baader Green CCD 2" Telescope Filter with LPFC Mechanical Properties:

Each individual filter planeoptically polished to 1/4 wave and parfocal.

Each filter coated separately. Filters are NOT just cut or bored out from a large coated plate.

Baader individual hard coatings do ensure sealed coating edges, impermeable from moisture and environmental forces.

Baader-filters feature hard coatings that may be cleaned with Baader Optical Wonder fluid without scratches.

Optical Properties:

Baader RGB CCD filters are COMPLETELY free from reflections due to an elaborate coating design.

RGB-imaging allows equal weighting factors for each channel, very important for automated imaging.

Unique filter design for absolute maximum contrast with extremely high gradients,to allow clear differentiation of colours.

O III emission overlaps on B/G-filters with maximum transmission to allow efficient and natural colour imaging.

R-filter delivers maximum transmission for H-alpha and S II while cutting IR with highest efficiency

Gap between G/R-filters serves to reduce light pollution from Mercury and Sodium lamps and improves color balance and color separation.
