The right light transmission for every situation

Three neutral-density filters dim the entire visible spectrum without altering the colour of the Moon. The darkest filter is suitable for large-aperture telescopes and low-power eyepieces, whilst the lighter ones are suitable for smaller telescopes and higher-power eyepieces. ND filters can also be used to reduce the glare from Venus when observing its crescent phases, as well as to reduce the brightness of daytime views during terrestrial observation.

Moon & Sky Glow filter for improving contrast

The Moon & Sky Glow filter reduces light transmission at selected wavelengths and emphasises the Moon’s subtle features, giving it a very pale purple hue. In areas affected by light pollution, it also improves the contrast of deep-sky objects by filtering out, for example, the wavelengths emitted by low-pressure sodium streetlights.

Main features

• Four filters designed for observing the Moon, all in one pack.
• ND filters transmit 13 %, 25 % or 50 % of light, so the brightness can be adjusted according to the phase of the Moon, the aperture of the telescope and the magnification.
• The Moon & Sky Glow filter brings out details on the Moon’s surface and aids deep-sky observation under light-polluted skies.
• Reduced glare makes viewing more comfortable and reduces eye strain.
• The aluminium frames protect the filter glass, and the threads at both ends allow the filters to be stacked.
• The plastic carrying case contains a map of the Moon and explanations to help you identify the Moon’s most popular features.
