Scope of delivery: Optical tube, Goto mount, accessories
Excellent for entry-level astronomy: 90mm aperture provides about 200 times more light than the naked eye!  
Observe craters, valleys and grooves on the moon at a distance of almost 400,000km as if you were very close! The BRESSER MESSIER AR-90s with EXOS II Goto mount offers you detailed images but not only of the moon: Take a closer look at the division of Saturn's rings millions of kilometers away or discover Jupiter's "Great Red Spot," a massive cyclone in its atmosphere. Track the seasons on Mars and spot the crescent of Venus.

But the AR-90s also performs very well as a compact travel instrument. Especially due to the shorter focal length of only 500mm, impressive wide field observations of open star clusters and the Milky Way can be realized.
 
The MESSIER AR-90s already collects several times more light compared to the instrument with which Galileo Galilei made his famous discoveries almost four hundred years ago. 
The permanently installed exchange cap reduces any possible dew formation and prevents lateral stray light from falling in, which further increases the contrast of the image. 
A GP prism rail is located on the tube clamp of the AR-90s/500 for attachment to the mount.
