Celestron Light Pollution Filter

Get the most out of your celestron rowe ackermann schmidt astrograph 11 even under light polluted skies with this light pollution imaging filter custom designed for the rasa.

Celestron light pollution filter.

The light pollution imaging lpi filter for the 8 rasa blocks light from some of the most common sources of light pollution between 400 700nm i e the visible spectrum including high and low pressure sodium vapor streetlights mercury vapor streetlights and natural airglow caused by oxygen in the atmosphere. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97 across the entire bandpass with total blockage of prominent light pollution lines. To help combat light pollution celestron offer a rasa light pollution imaging filter for the rasa 8 and rasa 11 scopes which has been developed to block the light pollution from some common sources including high and low pressure sodium streetlights as well as natural airglow. The perfect filter for viewing nebula from light polluted skies or for boosting the contrast of nebula from dark sky sites.

The design of the filter includes layers that block specific bandpass lines of the visible spectrum. The light pollution imaging lpi filter for the 8 rasa blocks light from some of the most common sources of light pollution between 400 700nm i e the visible spectrum including high and low pressure sodium vapour streetlights mercury vapour streetlights and natural airglow caused by oxygen in the atmosphere. A light pollution telescope filter is probably the most generic of these types of filters and is designed to block out certain wavelengths of light such as the light being created by sodium vapor mercury fluorescent and other man made sources of light that are typically found in outdoor lighting. No matter which camera you use this filter s generous 68 mm clear aperture allows it to easily accommodate today s largest sensors.
