EXPLORE SCIENTIFIC Filter 1.25" Red No.25


Using this filter, blue/blue green light is totally blocked. This filter is very useful in steadying atmospheric seeing conditions when used with larger telescopes and is great for isolation of darker clouds on Jupiter (and to a certain extent Saturn).  It is also very useful in trying to enhance darker areas on Mars and showing up brighter contrast feature, such as the polar caps.

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

Colour Filters darken the light that reaches the eye, or the sensor of the camera, slightly. This eliminates stronger wavelengths, with the result that your target experiences a boost in contrast at certain wavelengths of light which are allowed through - which automatically reveals greater detail.
