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 (2 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

AskarAskar Colour Magic C2 Duo-Band Filter S-II O-III,2 Inch Narrowband Nebula Filter Astrophotography Astronomy Filters for One-Shot Color Cameras,Increase Contrast and Reduce Light Pollution
Main highlights- SII+OIII: Colour Magic C2 Duo-band filter (SII+OIII) has a high transmittance of over 90% at its center wavelength (500.7nm and 672nm). It can effectively improve the quality of the image by making the sky background of the image darker while maximizing the contrast throughout the image， enhancing the contrast of your pictures, and making it easier to display the details of the stars.
- LIGHT POLLUTION REDUCTION: Telescope astronomy filters can effectively reduce the interference of artificial light pollution such as city lights, natural light sources or street lights, facilitating better observation,this filter can also selectively filter light pollution and cluttered signals through the emission lights of the nebula to achieve the ideal shooting effect.
- EASY TO USE: Dual-band filters can completely blocks virtually all other visible wavelengths of light so views of nebulas are optimized and reduce the difficulty and tediousness of user post-processing, reducing the difficulty for customers to get started
- BETTER IMAGE: After using this filter, it can produce an extremely clear and sharp effect image, so this narrow band filter is considered one of the most popular astronomical accessories. It can be used not only for astronomical observation, but also for astronomical photography.
- ASTROPHOTOGRAPHY: This filter can improve the contrast when observing gaseous nebulae and planetary nebulae under any sky conditions,even in places with light pollution, high contrast observation effects can be achieved
