Thanksgiving Deal Baader Red 610nm Long-pass Filter - 2" Round Mounted Collection [xXDPaY1b]

Baader Red 610nm Long-Pass Filter - 2" Excellence

Discover the Baader Red 610nm Long-Pass Filter, a premium astronomy tool designed for the discerning observer. This 2" round mounted filter stands out for its exceptional quality, offering unparalleled performance compared to standard flame polished filters. Crafted with precision, this filter ensures a seamless insertion into your optical path, guaranteeing no astigmatism or other defects. The 2mm thick glass and fine optical polish are key to its remarkable clarity and image quality.

• Superior Optical Quality: Baader filters outperform the competition with their fine optical polish and 2mm thick glass, ensuring image clarity and reducing astigmatism.
• Reduced Ghosting: The filter's substrates are free of striae and polished plane-parallel to within 30 seconds of arc, eliminating double images and ghosting.

Technical Specifications and Performance

The Baader Red 610nm Long-Pass Filter is engineered for maximum performance, with a clear aperture that is the largest on the market, ensuring complete freedom from vignetting at any focal length. Its innovative design features a milled "crown" with notches for easy handling in low-light conditions. The filter is treated with a 7-layer Multi-Coating, reducing residual reflections to an impressive 0.25%, which is the most elaborate coating ever applied to amateur color filters. This coating prevents false reflections under any incident angle of light, providing a brighter, more contrast-rich image.

• Optical Coating: The 7-layer Multi-Coating minimizes reflections and enhances light transmission, resulting in a filter free of any false reflections.
• High Transmission Efficiency: With peak efficiencies of 98% for the longpass filters and 70% for the bandpass filters, these filters offer maximum contrast and detail isolation.

Practical Applications and Benefits

The Baader Red 610nm Long-Pass Filter is an essential tool for planetary observation, providing the necessary light to recognize subtle surface details even under high magnification. Its ability to be stacked without image degradation or ghosting makes it ideal for providing even narrower passbands. Whether you're using a digital camera or a binoviewer, this filter maintains sharpness and clarity. The 2" size is particularly convenient for binoviewing, as only one filter is needed, thanks to its exceptional optical quality.

• Planetary Observation: Enhance your planetary observations with maximum contrast and detail isolation, ideal for high magnification work.
• Multi-Use Capabilities: Combine with other Baader filters for various applications, or stack filters for narrower passbands without any degradation.
