What are these color filters for? Do we really need color filters?
Color filters slightly darken the light that reaches your eyes or the sensor of your camera. This filter helps eliminate any risk of overexposure. They make the image even more contrasted, and no detail, no matter how small, can escape you.

The following filters are included in Set No. 1:

EXPLORE SCIENTIFIC Filter 31.7 mm - Green No. 56

The green filter significantly increases the contrast between the red and blue regions of cloud structures on the gas planets Jupiter and Saturn. On the Moon, the contrasts are clearly visible on the crater rims.

EXPLORE SCIENTIFIC Filter 31.7 mm - Dark Blue No. 38A

The dark blue color facilitates the observation of high nebulosity on the planet Mars. The contrast improves. The dark red structures are represented even darker, making this filter the perfect tool for observing the large red markings on the gas planets Jupiter. The ring of Saturn is highlighted, and the atmospheric structures of Venus become more refined. Compatible with telescopes with an aperture of 8".

EXPLORE SCIENTIFIC Filter 31.7 mm - Orange No. 21

Facilitates the recognition of dark areas on the planet Mars. This filter also allows you to identify even more details of the cloud bands on Saturn and Jupiter.

EXPLORE SCIENTIFIC Filter 31.7 mm - Light Yellow No. 8

When observing the surface of the Moon, the contrast is significantly improved. The same goes for the planet Mars. On the immense planet Jupiter, the contrast between the different cloud bands is greatly increased, allowing you to see more and more new things. With a telescope of at least 8" in diameter and under excellent observing conditions, you may even be able to identify objects on Saturn.
