This UV/IR Cut off filter blocks undesirable ultraviolet and infrared rays that may interfere with obtaining the high contrast and quality images possible with a digital sensor
1.25" moon and skyglow filter is a multi band pass filter transmitting a high percentage of light in the visual spectrum;the filter enhances contrast when observing brighter objects including the moon and planets
UHC filters or light pollution reduction filters are designed to selectively reduce the transmission of certain wavelengths of light;especially those produced by artificial light
Evaporation with Ion assisted deposition coating technology for durability and resistance to scratching;as well as stability on CWL (central wavelength) no deviation affected by temperature change
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
وصف
The UV-IR-Cut filter uses the very latest coating technology to deliver the high filtration quality and lifetime durability. 1.25” moon and skylow is a multi-band pass filter transmitting a high percentage of light in the visual spectrum. UHC Telescope Filter Improves Image Contrast of Nebula and Deep Sky Objects. CLS Light Pollution Reduction Filter for Observation of Deep-Sky. SV220 is suitable for those astronomers who are already imaging using color cameras and don't want to transition to a monochrome camera set. Be the efficient astronomer with SV220 Dual Band Filters!
