1.25″ UHC Ultra High Contrast Filter
Superb Views of The Lagoon Swan Nebulae
The 1.25″ Ultra High Contrast (UHC) filter is a versatile astronomical filter that blocks out unwanted light pollution, enhancing the visibility of deep-sky objects. Thanks to its specific bandwidth, the UHC filter is particularly effective at observing emission nebulae, planetary nebulae, and other objects that emit strong H-alpha and O-III emission lines.
Product Features:
* Exceptional Contrast Enhancement:
The UHC filter effectively suppresses light pollution, allowing you to observe faint celestial objects with increased contrast. The result is a significant improvement in the visibility of emission nebulae, such as the Lagoon Nebula and Swan Nebula.
* Targeted Emission Line Blocking:
The filter’s narrow passband specifically targets H-alpha and O-III emission lines, which are common in emission nebulae. By blocking out other wavelengths, the UHC filter enhances the appearance of these objects, making them more vibrant and detailed.
* Versatile Usage:
The UHC filter is suitable for use with a wide range of telescopes, making it a versatile addition to any astronomer’s toolkit. Its 1.25″ diameter fits standard telescope eyepieces and other accessories.
* Easy Installation and Removal:
The filter features a convenient screw-on design that makes it easy to attach and remove from your telescope. No tools or complex adjustments are required.
* Durable Construction:
Made from high-quality materials, the UHC filter is built to withstand demanding observing conditions, ensuring long-lasting performance.
Key Usage Points:
* Ideal for observing emission nebulae, planetary nebulae, and other objects with strong H-alpha and O-III emission lines.
* Enhances contrast and visibility of deep-sky objects.
* Suppresses light pollution for clearer observations.
* Easy to install and remove.
* Durable construction for extended use.
Additional Features:
* 10nm bandwidth for targeted emission line blocking.
* High-quality optical glass for sharp and clear images.
* Scratch-resistant coating for long-lasting performance.
