Introducing the SV115 O-III Telescope Filter

The SV115 O-III Telescope Filter is designed for visual observation of emission nebulae, planetary nebulae, and supernova remnants. In conditions of severe light pollution, this narrowband filter can significantly enhance the contrast between nebulae and the night sky, without increasing the brightness of the object or removing the effects of light pollution.

Key Features: - 18nm Narrowband OIII Filter: Allows for the transmission of light centered on a wavelength of 500nm, corresponding to OIII emission lines, while reducing the transmission of artificial and unwanted natural light. - Suitable for Use with Accessories: Can be used with astronomical cameras, focus reducers, and eyepieces to achieve optimal viewing in both clear and dark observation conditions. - Sturdy and Durable Construction: Made of high-quality materials with strong, long-lasting threads. - High-Grade Optical Glass: Featuring dichroic interference and anti-reflection coatings for superior image quality. - Protective Storage: Comes with a plastic case with high-pressure EVA lining to safeguard the filter.

The SV115 O-III Filter is particularly useful for large-aperture telescopes, where the light of the Moon can be overwhelming. By selectively filtering out unwanted wavelengths, the filter enhances contrast during visual observation and astrophotography of gaseous and planetary nebulae, even in areas with strong light pollution.
