Antlia Filters LRGBR+ Dark Series: Advanced Full-Spectrum Imaging for Deep Sky

The Antlia LRGBR+ Dark series filters set a new standard in deep sky astrophotography. These premium filters extend across a full spectrum curve from 390nm to 1000nm, sensitizing them to both UV and IR light. This broad range ensures a high signal-to-noise ratio and superior contrast, making them ideal for full-spectrum deep sky photography. Crafted from quartz glass, known for its ultra-low thermal expansion coefficient, the LRGBR+ Dark series filters promise exceptional thermal and mechanical stability, offering remarkable durability even in the most challenging environmental conditions.

Key Features:

Full Spectrum Range: Sensitive from 390nm to 1000nm, capturing both UV and IR light.
Enhanced Signal-to-Noise Ratio: Ideal for high-contrast deep sky imaging.
Quartz Glass Construction: Ensures superior thermal and mechanical properties.
Red+700-1000nm Filter: Captures valuable signals beyond regular LRGB filters' range.
Post-Processing Compatibility: Combine R and R+ channels for enhanced red channel imaging.
Pairing with SHO Narrowband Filters: Ideal compatibility with Antlia SHO 2.8nm and 2.5nm Ultra Narrowband filters for better parfocality.
Environmental Resilience: Designed to withstand challenging conditions.

Usage Guidelines:

Not for Solar Imaging: Strictly not recommended for solar observation.
Visual Observation Warning: Not suitable for night visual observation.
Safety Precaution: Direct sun observation with this filter can lead to serious eye damage.

The Antlia LRGBR+ Dark series filters represent a leap forward in astrophotography capabilities, allowing astronomers to explore and capture the universe with unprecedented detail and clarity. Their ability to harness the full spectrum of light opens up new possibilities for imaging and research, making them an essential tool for both amateur and professional astrophotographers.
