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.
