EXPLORE SCIENTIFIC Set di Filtri N4 #74793

Explore Scientific Filter Set N4 is recommended for lunar and planetary observations through telescopes with an aperture of 200mm (8") and higher.

Set N4 includes the following filters:

Explore Scientific Filter 1.25" Green No.56
The green filter is to increase the contrasts enormously between the red and the blue regions of the cloud structures on the gas planets Jupiter and Saturn. Seeing our Earth Moon through the green filter, the contrasts of each ray crater become clearly more visible.

Explore Scientific Filter 1.25" Dark Blue No.38A
The color of light blue really supports watching the high clouds on Mars. The contrast increases. The dark red structures will be shown even darker, so this is the perfect filter for watching the big red Flecks on the gas planet Jupiter. The rings of Saturn will be accentuated, the structures of the Venus Atmosphere will be even finer. Works well starting with a 10" aperture.

Explore Scientific Filter 1.25" Orange No.21
This one really supports the detection of the dark areas on the planet Mars. The details of the clouds of Saturn and Jupiter are also so much more visible through the Filter.

Explore Scientific Filter 1.25" Light Yellow No.8
Watching the Moon surface through the filter, the contrasts will enormously increase. Same with planet Mars. On the huge planet Jupiter, when using the filter, you can even see the contrasts between the cloud-bands and a lot more details. Starting with a telescope diameter of 8“ and a clear sight, you even get to see various details of Saturn.

What ist a color Filter for and do we really need it?

Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details.
