Antlia Filters IR850 - 1.25": Premium Infrared Imaging for Planetary Photography

The Antlia IR Pass 850nm filter, a companion to the IR Pass 685nm, is a specialized absorptive filter designed for advanced planetary photography. This filter allows infrared light with wavelengths over 850nm, offering astrophotographers the ability to capture the sharpest and highest contrast images of planetary bodies. Particularly effective in long-wavelength spectral ranges, the IR850 filter significantly reduces the impact of atmospheric air turbulence on image sharpness.

Key Features:

• Infrared Light Pass: Permits wavelengths beyond 850nm, ideal for high-resolution imaging.
• Planetary Imaging Enhanced: Reduces wavefront distortions, resulting in sharper and higher contrast planetary images.
• Daylight Imaging: Capable of imaging planets during daylight with a dark background sky.
• Filter Ring Design: 1.25” (28.5*0.6) size with an ultra-thin cell to minimize vignetting.
• Durability: Black anodized finish and laser engraving ensure longevity and no fading.
• Not for Visual Use: Infrared sensitivity beyond human vision, not suitable for visual observations.
• Safety Caution: Not recommended for solar observing or imaging; direct solar observation can cause serious eye damage.

The Antlia IR Pass 850nm filter is an invaluable tool for astrophotographers seeking to push the boundaries of planetary imaging, offering unparalleled clarity and detail in captured images. Its ability to minimize atmospheric interference makes it a crucial addition to any astrophotography setup focused on planetary observation.
