CLS Filters
These filters are suitable for photography from areas polluted by artificial light with cameras that are also sensitive in the infrared. The contrast of all deep sky objects is increased.
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.
