Product information “BRESSER Messier AR-90\/900 EXOS1\/EQ4 Telescope”<\/div>\n
\n

NEW \u2013 now including a high-quality aperture Solar-filter<\/b>\u00a0<\/span>for safe observation of sunspots, eclipses and planet transits. Great telescope for\u00a0<\/span>night and solar observation<\/b>.<\/p>\n

Excellent for entering into the hobby of astronomy: 90mm aperture delivers 200 times more light than the naked eye! Observe craters, valleys and rims on the moon from nearly 400,000 km away just as you would look out of the window of a spaceship!
\nThe\u00a0<\/span>BRESSER\u00a0Messier AR-90\u00a0<\/span><\/b>does not only provide highly detailed views of the moon: Gaze at the division of the rings of saturn millions of kilometers away or explore the Great Red Spot of Jupiter, a giant tornado in Jupiter’s atmosphere. Watch the seasons on Mars and find the sickle of Venus.
\nThe\u00a0<\/span>Messier AR-90\u00a0<\/span><\/b>gives you images that are many times brighter than the instrument Galileo Galilei was using for his famous explorations almost 400 years ago.<\/p>\n
