The Moon & Skyglow is a multi-bandpass filter transmitting a high percentage of light in the visual spectrum; it is among our most economical and versatile well made astronomy filters. The filter enhances contrast when observing brighter objects including the moon and planets. It also will suppress sky glow from artificial lighting and background glow reflected when the Moon is up. The filter has a mild effect of darkening the background of the night sky so that the fainter objects are more clearly seen contrasted against the blackness of space.
Very high light transmission exceeding ninety five (95) per cent of that light some the portions of the spectrum - while blocking unwanted skyglow and many street light emissions. The filter has a notable effect at enhancing contrast when observing brighter objects including the moon and planets.
By rejecting most other light this will cause certain objects to appear more clearly against a blacker background of space. The visual effect is subtle to the less experienced observer. However with experience the differences of observing with and without this filter become easier to comprehend.
The filter is also suited for CCD imaging applications due to it's contrast enhancing properties and modest effect at darkening the objects.
This filter has been designed for Canadian Telescopes in Canada and are made in Japan.
