Vai al moduloBaader Contrast Booster Filter – Enhanced Contrast with Zero False Color
The Baader Contrast Booster is a high-performance optical filter specifically designed to eliminate chromatic aberration in fast achromatic refractors. With a light transmission of over 95%, it significantly enhances image contrast and sharpness, outperforming standard green moon filters and delivering a more natural color balance.
Ideal for:
- Lunar and planetary observation: Removes the typical blue-violet halo from achromatic refractors and reveals subtle details on Jupiter and Mars (including the Great Red Spot).
- Solar observation: Use only in combination with a Baader AstroSolar safety filter for improved clarity and more realistic color rendering.
- Terrestrial viewing: Balances color and boosts contrast in daylight observations, even with beginner-level telescopes.
Superior Optical Performance
- Completely removes false color in budget achromatic refractors.
- Boosts contrast without dimming the image – thanks to >95% light transmission.
- Reduces atmospheric skyglow, resulting in a darker background and higher visibility of fine features.
- No image quality loss even at magnifications above 200x.
- Significantly better than standard green filters typically bundled with entry-level scopes.
Construction and Coatings
- Optical glass substrate: Neodymium-doped glass.
- Back side coating: 7-layer multi-coating with only 0.25% reflection.
- Front side coating: 23-layer dielectric coating.
- Ion-beam hardened coatings on both surfaces – scratch-resistant and durable.
- Safe to clean anytime using Baader Wonder Optical Fluid.
The Contrast Booster is a professional-grade, multi-purpose filter that brings out the best in any achromatic refractor. Highly recommended for beginners seeking a serious performance upgrade from basic colored filters and aiming for sharper, more vibrant views.
