Collection: 2 Inch Astrophotography Filters

The Optolong 2" LRGB Filter Set is designed to improve the quality of astronomical images by separating the light spectrum into its primary components. This allows for detailed and accurate color representation in both deep-sky and planetary imaging. By blocking unwanted light pollution and infrared wavelengths, these filters enhance the visibility of celestial objects and improve the overall image quality.

Captures specific wavelengths at 500.7nm (OIII) and 656.28nm (H-alpha) with a Full Width at Half Maximum (FWHM) of 7nm. Designed for use with fast focal ratio imaging systems, including RASA, HyperStar, and other systems with focal ratios from f2 to f3.3.

It boasts high transmittance in the primary emission lines of Hydrogen-alpha (Ha), Sulfur II (SII), Oxygen III (OIII), and Hydrogen-beta (H-Beta). This enhances the signal-to-noise ratio (SNR) and contrast in your images.

Take your astronomical observations and astrophotography to new heights with the Optolong H-Alpha 7nm Filter 2 Inch. Order now to enjoy clear, high-contrast images of the night sky and capture the beauty of deep-sky objects with unprecedented detail.

The Optolong SII Filter 2 Inch 6.5nm is designed to isolate the Sulfur II (SII) emission line at 672nm, significantly enhancing the contrast and visibility of deep-sky objects. By blocking unwanted wavelengths, including those from light pollution, this filter ensures that you can capture clear and detailed images of nebulae, supernova remnants, and other emission line objects.

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 L-Ultimate isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue), blocking out unwanted light and maximizing the signal from nebulae.

It allows a 7nm bandwidth of light centered on a wavelength of 500nm, effectively blocking all other light and significantly reducing light pollution. Approximately 90% transmission at the major OIII emission line of 500nm, ensuring bright and clear images of nebulas.

The ZWO 2" H-Alpha Ha Filter 7nm is primarily used for capturing and observing emission nebulae. By isolating the H-alpha emission line, this filter enables astronomers and astrophotographers to see and photograph structures within nebulae that are often obscured by other wavelengths of light.

The ZWO 2" Narrowband SII Filter 7nm is primarily used for capturing and observing emission nebulae. By isolating the SII emission line, this filter enables astronomers and astrophotographers to see and photograph structures within nebulae that are often obscured by other wavelengths of light.

The ZWO SHO 2" Inch Filter Set Kit (Ha SII OIII) Narrowband 7nm is a game-changer for astrophotographers seeking to capture the night sky in exquisite detail and color. This set of narrowband filters is designed to isolate specific wavelengths of light emitted by celestial objects, allowing for high-contrast, detailed images of nebulae and other deep-sky objects.

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.

Perfect for capturing detailed images of nebulae and other celestial objects in the OIII and H-alpha emission lines. Optimized for use with fast focal ratio telescopes such as RASA, HyperStar, and others in the f2 to f3.3 range.

This filter is designed for imaging and is not suitable for visual observation. It is specifically crafted to improve deep-sky imaging by isolating key emission lines and reducing light pollution. For best results, use this filter with a camera setup that is sensitive to the wavelengths it isolates.

Over 85% at the center wavelength of 500.7nm and 656.3nm. FWHM of 6.5nm±0.5nm for OIII and 8.5nm±0.5nm for Hα. Darkens the sky background to highlight the details of celestial objects.

Investing in the ZWO LRGB Filter 2" Inch set is a smart choice for any serious astronomer or astrophotographer. The ability to isolate specific wavelengths of light and reduce the impact of light pollution makes these filters essential for capturing stunning, true-color images of celestial objects.

The set includes four mounted filters: Luminance (L), Red (R), Green (G), and Blue (B). Each filter is crafted to pass specific bands of light, allowing for detailed and vivid imaging.

The Antlia ALP-T Dual Band 5nm Filter is a dual line-pass filter crafted to enhance the performance of one-shot color (OSC) cameras such as DSLRs and astronomical OSC cameras. It can also serve as a narrowband filter for monochrome cameras, providing flexibility and efficiency in your imaging sessions.
