Antlia Filters IR685 - 1.25": Advanced Infrared Imaging for Planetary Photography

The Antlia IR Pass 685nm filter is a specialized tool designed for astrophotographers focusing on planetary imaging. This absorptive filter permits infrared light above 685nm, enhancing image sharpness and contrast by mitigating the effects of atmospheric turbulence. Ideal for capturing the finest details of planetary surfaces, the IR685 filter is an essential component for producing high-quality, sharp images in astrophotography.

Key Features:

Infrared Pass: Allows wavelengths above 685nm for clear, detailed imaging.
Planetary Photography Enhancement: Ideal for capturing sharp and high-contrast planetary images.
Reduced Atmospheric Disturbance: Minimizes the impact of air turbulence and wavefront distortions.
Complementary Imaging: Works exceptionally well with RGB and U-Venus filters to enhance overall image sharpness.
Daylight Imaging Capability: Effective for imaging planets during daylight due to the dark background sky created by the filter.
Highly Specialized: Not suitable for visual observation due to reduced eye sensitivity in this spectrum.
Safety Warning: Not recommended for solar observing or imaging; direct sun observation can cause serious eye damage.

The Antlia IR Pass 685nm filter opens up new possibilities in planetary astrophotography, allowing enthusiasts and professionals alike to explore and capture the subtle details of planetary features with unprecedented clarity. Its ability to reduce atmospheric interference makes it a valuable asset in any astrophotographer's toolkit.
