Astro Essentials IR720 IR Pass Filter 1.25/2"

Astro Essentials IR720 IR Pass Filter 1.25/2" – Infrared Imaging Excellence

Brief Overview

The Astro Essentials IR720 IR Pass Filter 1.25"/2" is an essential tool for planetary photographers. Designed to pass infrared wavelengths of more than 720nm, this filter significantly enhances image sharpness and contrast by reducing the impact of atmospheric turbulence. Ideal for both night-time and daylight imaging of planets, it offers a unique advantage in capturing detailed celestial images. This wave length is not suitable for visual astronomy.

Key Features

• 720nm IR Pass Filter: Passes infrared wavelengths greater than 720nm.
• Enhanced Image Sharpness: Reduces atmospheric air turbulence impact, providing clearer, sharper images.
• Daylight Imaging: Enables planetary imaging during daylight hours.
• Combines with Other Filters: Improves overall image sharpness when used with RGB and U-Venus filters.
• Non-Suitable for Sun Observation: Important safety note for users.

Detailed Description

The Astro Essentials IR720 IR Pass Filter 1.25"/2" is specially designed for planetary photography, making it an indispensable tool for both amateur and professional astronomers. This filter allows infrared wavelengths above 720nm to pass through, while blocking visible light. At these longer wavelengths, the sensitivity of the unaided human eye is reduced, making this filter unsuitable for direct visual observations but perfect for photographic purposes.

One of the key advantages of this filter is its ability to reduce the impact of atmospheric turbulence (seeing), which often distorts celestial images. By operating in the long-wavelength spectral range, the IR720 filter minimises wavefront distortions caused by the atmosphere, resulting in the sharpest and highest contrast images possible. This makes it highly recommended for any planetary photography, particularly when fine detail and high contrast are required.

Additionally, the IR720 filter allows for planetary imaging during daylight hours. The filter creates a dark background sky against which planets can be imaged, providing flexibility and extended imaging opportunities. When combined with a luminance image and other filters like RGB and U-Venus, the IR-Pass filter significantly enhances overall image sharpness and detail.

It is crucial to note that this filter is NOT suitable for observing or photographing the Sun. Using the IR720 filter for solar observation can result in permanent eye damage. Always follow safety guidelines to ensure proper use.
