Excellent for entering into the hobby of astronomy: 90 mm 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!
The BRESSER MESSIER AR-90s 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.
Richfield telescope with a short focal length of 500 mm. Suitable for traveling and to observe large open star clusters and the Milky Way.
The MESSIER AR-90s gives you images that are many times brighter than the instrument Galileo Galilei was using for his famous explorations almost 400 years ago.
This telescope is an optical tube without mount and tripod.
