Optical Vision Light Pollution Filter For Telescope: 1.25
The Light Pollution Filter is a contrast-enhancing anodized aluminium,
optical glass filter designed to block out the wavelengths of light
emitted by mercury-vapour light and other common causes of light
pollution, whilst providing higher transmission at critical
hydrogen-alpha and hydrogen-beta lines than competing filters. 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.
Light Pollution Filter:
These filters allow maximum transmission of the important wavelengths of
H-alpha, H-beta and doubly ionized oxygen – the ones most commonly
emitted by nebulae. Views of galaxies and star clusters are also
enhanced, but to a lesser degree. Also improves contrast on reddish
planetary detail. Works well in telescopes of all apertures but is
highly recommended for use on smaller telescopes up to 114mm diameter,
where conventional filters swallow up too much light. Supplied with
