Details

A green filter, such as the Explore Scientific Filter 2" Dark Green No.58A increases the contrasts enormously between the red and the bluer regions of the cloud structures on the gas planets Jupiter and Saturn. Observing our  Moon through the green filter, the contrast of each ray crater become more clearly visible. This filter should be used at an aperture of 8“.


What is a colour filter for and do we really need it ?


Colour filters attenuate the light that reaches the eye or the sensor of the camera slightly. This eliminates for stronger transmissions, which leads to greater contrast, which automatically reveals greater detail.
