Ultimate Baader Ir-pass Filter (685 Nm) Customer Approved [hx5n1eOP]: Sharpen Your Observations

The Ultimate Baader Ir-pass Filter (685 Nm) Customer Approved [hx5n1eOP] is a premium optical accessory designed to enhance the clarity and detail of your astronomical observations. Crafted with precision, this filter is an essential tool for planetary imagers seeking to capture the sharpest images possible. Its unique ability to pass wavelengths above 685 nm significantly reduces atmospheric turbulence, commonly referred to as "seeing," resulting in a much sharper and more defined image. With this filter, you can expect to see the dark structures on Mars, Jupiter, the Moon, and even the Sun with unprecedented clarity.

Key Features and Specifications

The Baader IR-Pass Filter boasts several features that make it stand out in the market. It features a high optical quality with a Striae-free substrate, ensuring the highest contrast and clarity. The dielectrically coated, planeoptically polished design not only reduces reflections but also improves image quality. Here are some of the key benefits and specifications:
  • Transmission Range: > 685 nm, starting at 670 nm in the deep red, just within the visual range for proper focusing.
  • Filter Thickness: 2 mm, providing a stable and secure fit in your imaging setup.
  • Filter Size: Available in 1.25" and 2" mounts to fit a wide range of telescopes and imaging systems.
  • Filter Usage: Ideal for contrast enhancement, IR-Pass, and planetary imaging.
The Baader IR-Pass Filter is also highly recommended for any planetary imager looking to elevate their observations to the next level.

Practical Uses and Applications

Beyond its astronomical applications, the Baader IR-Pass Filter finds utility in nature photography, revealing stunning differences in plants, sky, and clouds. This filter is compatible with cameras sensitive to infrared light above 670 nm, such as modified DSLRs or webcams. Additionally, the filter darkens twilight sky backgrounds, allowing for stunning images of moon and planets at dawn or dusk. Deep sky images can also benefit from the filter, revealing young hot stars in dust clouds and star-forming regions. With the Baader IR-Pass Filter, the possibilities are endless, and the results are truly remarkable.
