Sky Guides von Bresser
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 400,000km away just as you would look out of the window of a spaceship!
The MESSIER AR-90 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. The MESSIER AR-90 gives you images that are many times brighter than the instrument Galileo Galilei was using for his famous explorations almost 400 years ago.
The new BRESSER NANO AZ telescopic mount has been developed to ensure quick and easy operation. The mount is as easy to use as a photo tripod, it is just more stable and easily carries telescopes weighing up to 4 kg. The mount can be easily swivelled by hand to the left, right, up and down, making it really easy to use and with a weight of only 3.4kg, the mount is also easy to transport. Ideal for the easy entry, as a travel mount or for quick observations. The telescopes are securely held by a clamp for 44mm prism rails, the so-called GP Level. This is an international manufacturer-independent standard, whereby all telescopes with such a GP prism rail can be installed on this mount. The sturdy and height-adjustable stainless steel tripod included in the scope of delivery is the ideal base for the BRESSER NANO AZ mount.
