Astro Essentials IR850 IR Pass Filter 1.25"/2"

Astro Essentials IR850 IR Pass Filter 1.25"/2" – Infrared Astronomy Filter

Brief Overview

The Astro Essentials IR850 IR Pass Filter is designed for astronomy enthusiasts looking to enhance their planetary photography. This specialised filter allows infrared wavelengths of more than 850nm to pass through, significantly improving image sharpness and detail by reducing the impact of atmospheric turbulence. This is not recommended for visual astronomy.

Key Features

• 850nm IR Pass Filter: Passes infrared wavelengths greater than 850nm.
• Enhanced Planetary Photography: Ideal for capturing sharp, high-contrast images of planets.
• Daylight Imaging: Enables imaging of some planets during daylight against a dark background sky.
• Wavefront Distortion Reduction: Lessens the effect of atmospheric wavefront distortions (seeing) on image quality.
• Compatibility: Suitable for use with RGB and U-Venus filters for improved image detail.

Detailed Description

The Astro Essentials IR850 IR Pass Filter is a must-have tool for serious planetary photographers. This filter excels in passing infrared wavelengths above 850nm, making it unsuitable for visual observations due to the reduced sensitivity of the unaided eye at these longer wavelengths. However, this characteristic is precisely what makes it indispensable for capturing planetary images.

At longer wavelengths, atmospheric turbulence (or "seeing") has a minimal effect on image sharpness. The IR850 filter capitalises on this by allowing you to capture the sharpest and highest contrast images possible. This is particularly beneficial for planetary photography, where details are critical. When combined with luminance images made using the IR850 filter and other filters like RGB and U-Venus, the result is significantly enhanced image sharpness and detail.

Additionally, the IR850 filter enables the imaging of some planets during daylight, presenting them against a dark background sky created by the filter. This unique feature allows for more flexible photography sessions, regardless of the time of day.

IMPORTANT: This filter is NOT suitable for observing or photographing the Sun. Using it for solar observation can result in permanent eye damage.

Benefits

• Sharp, High-Contrast Images: Reduces atmospheric turbulence effects, resulting in clearer images.
• Daylight Imaging: Allows for planetary imaging during daylight.
• Enhanced Image Details: Improves overall image sharpness when combined with other filters.
• Specialised Use: Tailored for planetary photography, not for visual observations.
