Premium 1.25" Skyglow and Moon filter for Telescope Eyepieces

UK Postage is included in the low prices, for UK buyers the price is the total price you pay with no surprises at checkout gauranteed.

Along with a Barlow Lens (and a red LED headtorch of course) a Moon Filter is often one of the first purchases a new telescope owner will invest in.

Ideal for enhanced views of the Moon and brighter Planets.

This is a darker blue than the Crystalview version

The Skyglow filter is a slightly deeper blue than the Crystalview filter, meaning it absorbs a bit more light at longer wavelengths and therefore increases viwing contrast.

This can be useful when viewing the sky in areas where there is alot of light pollution.

High quality glass with metal frame

Premium quality

Moon & skyglow filters feature improved blocking of mercury-vapour light and 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 nebulas. Unlike stars, emission nebulas give off light in a very narrow range of wavelengths. Moon & SkyGlow filters allow maximum transmission of the important wavelengths of hydrogen-alpha, hydrogen-beta, and doubly ionized oxygen-the ones most commonly emitted by nebulas. Views of galaxies and star clusters are also enhanced, although not as much.
