The Optolong Planetary Filter Set Kit is an essential collection of high-quality filters designed for astrophotographers who seek to capture stunning images of our solar system's planets. This kit includes five filters: UV/IR Cut, Red (R), Green (G), Blue (B), and IR685, available in both 1.25" and 2" sizes. These filters are bundled under the "Solar System Seal," ensuring they meet the stringent demands of planetary photography. Whether you are using a monochrome camera or a color camera, these filters will help you achieve remarkable detail and contrast in your planetary images.

Essential for creating detailed SHO (Hubble Palette) images, enhancing the visibility of different elements within nebulae. Enhances contrast and detail in wide-field images when used with CCD or CMOS cameras.

The Optolong SII Filter 2 Inch 6.5nm is an essential tool for anyone serious about astronomy and astrophotography. Its ability to isolate the SII emission line and reduce light pollution makes it invaluable for capturing detailed images of deep-sky objects. With its high-quality construction and advanced features, this filter will significantly improve your stargazing and imaging experience.

The Optolong SII Narrowband 6.5nm Filter is a high-performance astronomical filter designed to enhance deep-sky imaging. Available in both 2" and 1.25" sizes, this filter is specifically engineered to isolate the Sulfur II (SII) emission line at 672nm. By drastically reducing other transmissions, including those responsible for light pollution, this filter allows astrophotographers to capture stunning, high-contrast images of nebulae and other celestial objects.

The filter boasts 95% transmission at the main nebula emission lines, including H-beta (486.1nm), OIII (495.9nm and 500.7nm), H-alpha (656.3nm), and SII (672nm).

Blocks 0.1% of major transmission lines of artificial light pollution such as Hg (435.8nm, 546.1nm, 577nm, and 578.1nm) and Na (589nm, 615.4nm, and 616.1nm).

Blocks wavelengths outside the 450-520nm and 620nm range, eliminating UV and IR light that can cause image distortion and reduce contrast.

Includes multiple layers of anti-reflection coatings applied via electron-beam gun evaporation with ion-assisted deposition, enhancing durability and scratch resistance. CNC machined from black anodized aero-metal, the filter cell is lightweight yet strong, with laser engraving to prevent fading.

The Optolong Variable Polarizing Filter 1.25" is an essential tool for anyone serious about astronomy and astrophotography. Its ability to control and fine-tune the brightness of celestial objects without altering their color makes it invaluable for capturing detailed images of the Moon, bright planets, and double stars. With its high-quality construction and advanced features, this filter will significantly improve your stargazing and imaging experience.

At the heart of the SHO Hubble Palette are three primary filters: Hydrogen-Alpha (Ha), Sulfur-II (SII), and Oxygen-III (OIII). Each filter targets a specific emission line, capturing the unique signatures of hydrogen, sulfur, and oxygen atoms as they interact within nebulae, supernova remnants, and other cosmic phenomena. By combining the data acquired through these filters, astrophotographers can create stunning images that reveal the intricate structures and dynamics of celestial objects with unparalleled clarity.

The SHO Filters Kit Set for DSLR Camera Lens is designed specifically for astrophotography, offering a comprehensive collection of narrowband filters optimized for capturing the beauty of deep-sky objects. This kit transforms your DSLR camera into a powerful tool for exploring the universe with unmatched clarity and precision.
