CONCEPT 52mm Light Pollution Filter Lens Filter K&F

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------

Size: 52mm light pollution filter. Compatible with 52mm lenses; please check your lens size beforehand. While the exterior may be a mix of old and new designs, the internal components are identical. Light Pollution Cut Filter: When trying to take astrophotographs from an urban area, the biggest problem is "light pollution," which is the bright illumination of the night sky by streetlights. This filter removes unwanted light (light pollution) such as streetlights, allowing the light from celestial objects to pass through when observing and photographing nebulae, star clusters, comets, etc. Light pollution filters are designed to cut out only the wavelengths of light from mercury lamps and sodium lamps, which are the source of light pollution. Because they cut out the light that causes light pollution, using a light pollution filter allows you to photograph celestial objects with longer exposure times than usual, even in astronomical observation sites affected by light pollution. Using precision annealed eco-optical glass specifically for glass lenses, both sides are optically polished to ensure surface quality. The multi-layer anti-reflective and double-sided waterproof coating effectively reduces ghosting interference in imaging caused by light reflection. The waterproof coating also makes it easier to wipe away dirt, fingerprints, and water stains, ensuring that the lens surface remains clean. While this isn't relevant when photographing the moon or planets, many other subjects require long exposures to capture faint starlight. However, in areas with severe light pollution, the background sky becomes too bright, obscuring the starlight. This is where filters commonly known as "light pollution filters" come in handy.
