OVL 1.25 Inch Light Pollution Filter : The Sky-Watcher Pollution Filter is a contrast-enhancing anodised aluminium, optical glass filter designed to block out the wavelengths of light emitted by mercury-vapour light and other common causes of light pollution. The filter provide higher transmission at critical hydrogen-alpha and hydrogen-beta lines than competing filters. The filter is threaded to fit standard 1.25" astronomical eyepiece and highly recommended for use on smaller telescopes up to 114mm diameter and works well in telescopes of all apertures. Bright, light-polluted skies appear much darker, and the contrast between object and sky is improved significantly. This contrast-enhancement effect is particularly apparent on nebulae. Unlike stars, emission nebulae give off light in a very narrow range of wavelengths. The OVL filter can improves contrast on reddish planetary detail as well.
OVL 1.25 Inch Light Pollution Filter is available at Microglobe at discounted price. Microglobe is largest online sport optics store of the UK.
