The OIII Filter 82mm can be used in conjunction with other narrow-band filters to capture a wider range of emission lines. By combining OIII with H-alpha (Hydrogen-alpha) and SII (Sulfur II) filters, astrophotographers can create multi-channel images that reveal different aspects of nebulae and other celestial objects. This technique enhances the overall detail and color range of the final image, providing a more comprehensive view of the target.

The OIII Filter boasts a 95% high pass narrow-band design, meticulously engineered to emphasize the spectral lines of Oxygen III in the night sky. This advanced feature ensures optimal performance, allowing you to capture breathtaking images with precision and clarity.

The filter allows 25nm bandwidth of light centered on the 486nm wavelength, providing bright and clear images of nebulae. Reduces the transmission of artificial light from mercury vapor and sodium vapor lights, as well as natural skyglow caused by neutral oxygen emission.

Ideal for capturing detailed images of emission nebulae and other deep-sky objects. Perfect for wide-field images of the night sky, highlighting nebulae and reducing light pollution. Useful for professional astronomers and researchers requiring precise and reliable optical performance.

The filters provide 95% transmission at the passband, ensuring bright and clear images. The gap between the green and red filters blocks the primary Sodium (Na) light pollution line at 589nm, enhancing color balance and separation.

The filter blocks infrared wavelengths from 700nm to 1100nm, eliminating the need for a separate IR-Cut filter. Precision Polishing: The filter substrate is fine-optically polished to 1/4 wave with less than 30 parallelism over both surfaces, ensuring superior image quality. Made from 2mm thick Schott B260 optical glass substrate, the filter offers excellent durability and reliability.

The Optolong 2" UV/IR Cut Filter is designed to block ultraviolet and infrared light, which can cause significant distortions in astronomical imaging. By ensuring that only the visible spectrum reaches your camera sensor or eyepiece, this filter enhances the clarity and accuracy of your observations and photos. It is particularly useful for deep-sky and planetary imaging, as well as for visual observation, making it an essential tool for any serious astronomer.

Thanks to its screw-on design, the Optolong Clear Sky Filter can be easily attached to lenses or telescopes with a 77mm thread diameter. This user-friendly design ensures that even beginners can quickly set up and start capturing stunning astronomical images without hassle.
