Excellent for getting started in astronomy: 90 mm aperture provide around 200 times more light than the naked eye!

Observe craters, valleys and grooves on the moon almost 400,000 km away as if you were very close! The MESSIER AR-90L offers you detailed images, but not only of the moon: take a close look at the division of the Saturn rings millions of kilometers away or discover the "Big Red Spot" of Jupiter, a mighty hurricane in its atmosphere. Track the seasons on Mars and see the sickle of Venus.
The MESSIER AR-90L already collects several times more light than the device with which Galileo Galilei made his famous discoveries almost four hundred years ago.
The permanently installed anti-dew cap reduces the formation of dew and prevents stray light from falling in, which further increases the contrast of the image.
There is a GP prism rail on the pipe clamp of the AR-90L / 1200 for fastening to the mount.

EXOS-2 mount and tripod.
The entry-level segment of the BRESSER Messier series. The smaller optics are stably mounted on the BRESSER EXOS-2. Gone are the days when price-conscious customers found it difficult to enter astronomy with undersized mounts. The EXOS 2 with sturdy steel tripod carries the offered optics up to a weight of 13kg for visual observation stably and without wobbling. For even more convenience when observing, the mount can be retrofitted with a motor set for the RA axis and DEC axis. In this way you always keep the celestial object in the eyepiece without having to manually adjust the course of the stars.
