10 Best Astrophoto Filter In The Us
Best Choice1
CelestronCelestron – Celestron Origin Nebula Filter – H-Alpha, H-Beta, Oxygen III Narrowband Astroimaging Filter – RASA 6” Optical Tube - Enhances Emission Nebulae
Main highlights- TARGETS KEY WAVELENGTHS: This filter transmits only the Hydrogen-Alpha, Hydrogen-Beta, and Oxygen III wavelengths, making emission nebulae “pop” from the dark background.
- ORIGIN NEBULA FILTER: This filter blocks light pollution, boosts image contrast, and darkens the sky background for noticeably better images, especially from urban and suburban skies.
- EASY INSTALLATION: Simply remove the optical window from Origin’s filter drawer and insert the Nebula Filter. It won’t disrupt the optical path of your Origin, and no additional adapters are needed.
- CONQUERS LIGHT POLLUTION: With this filter, you allow the “good” wavelengths from nebulae through but block light pollution and sky glow from reaching Origin’s sensor.
- BUILT FOR CELESTRON ORIGIN 6-INCH RASA: This filter was engineered specifically to work with Origin’s fast f/2.2 Rowe-Ackermann Schmidt Astrograph optics.

AstromaniaAstromania 1.25-Inch Specialized Planetary Imaging Filter Set 3-Pieces (Ultraviolet (UV) filter/Methane (CH4) filter/Infrared (IR) filter) - Each filter is specifically designed to enhance astrophotos
Main highlights- Ultraviolet "UV" filter enhances details of atmospheric structures: The included ultraviolet "UV" short pass filter transmits light wavelengths between 300nm and 400nm; while blocking all wavelengths above 300nm and below 400nm
- This set of three imaging filters includes the most vital filters for optimizing monochrome planetary portraits; includes an ultraviolet "UV" filter; infrared "IR" filter; and methane "CH4" filter
- Methane "CH4" filter boosts contrast and reveals high altitude atmospheric features: The narrowband methane "CH4" filter transmits the specific methane wavelength of 890nm with a 10nm bandwidth; while blocking all other wavelengths
- Includes protective plastic case with die-cut foam insert; since each included filter passes wavelengths outside of the visible spectrum; they are intended for imaging use only; a monochrome astrophotography camera is required when using this filter set
- Improve Clarity: The infrared "IR" long pass filter transmits light with wavelengths of 650 nm and above; used for high-contrast imaging of the Moon and planets; the infrared filter also provides excellent image steadiness when seeing conditions are poor

SVBONYSVBONY SV220 Telescope Filter, Dual-Band Nebula Filter, H-Alpha and O-III Narrowband Filter for One-Shot Color Cameras, Light Pollution Filter for Astrophotography (1.25 inches)
Main highlights- Reduce light pollution; SV220 telescope filter can greatly reduce the interference from natural light sources such as moonlight or artificial light pollution such as street lighting
- Improving contrast; an increase in contrast can be perceived as an increase in brightness; the filter makes the contrast of the nebula and sky background increase; not the nebula brighter
- For deep sky photography; use the dual-band filter to enable deep-sky photography in light-polluted cities or under a full moon
- Easy to use; the dual-band filter makes it possible to simplify and decrease the difficulty and cumbersomeness of post-processing for users
- Astrophotographic;the filter enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; the filter allows high-contrast imaging even in areas with strong light pollution

SVBONYSVBONY SV231 Color Correction Filter, 2 inches Telescope Filter for Moon Planetary Visual and Astrophotography, Correct Edge Chromatic Aberration to Enhance Detail Clarity and Contrast
Main highlights- OD＞4; the higher the filter cut-off depth; the smaller the noise and the higher the imaging contrast
- Good performance coating; telescope color correction filter has plasma-enhanced dielectric coatings result in hard; scratch-resistant and waterproof filters
- Full thread design; M48x0.75 specification; male thread; thread is not easy to wear; you can overlay other filter to use
- Focus photography; SV231 color correction filter can be used well before the focal point of the optical system; as a single filter in front of a binocular for focalphotography with digital cameras
- Correct chromatic aberration; SV231 telescope filter prevents unwanted color banding in the blue spectral range; minimizes blue wavelengths in out-of-focus areas
- Compatiable with SV503; SV48P; SV231 astrophotography filter can compatiable with telescope to realize astronomical observation
- AR anti-reflection coating design; transmittance exceeds 95%; improves the contrast and clarity of fast achromatic telescopes; ensures image quality and brightness; obtains more observable light
- 300-1200/NM wavelength; blocking light damage and eliminating blue and purple streaks
- 2 inch standard thread size; fits most telescopes; the grooves can be screwed into the eyepieces lens easily
