Watch details on Mars like the white polar ice-cap, the Cassini division on the ring of Saturn or the great-red-spot on Jupiter. Scanning the lunar terminator is simply a pleasure. You will never give the BRESSER Messier AR-90L Telescope away voluntarily.
Because of the extra long focal length ratio F/13.3 this telescope offers incredible sharpness and contrast but extremly low color-aberration.
BRESSER EXOS-2 GoTo Equatorial Mount. Mount, tripod and hand box with computer. This German mount has tracking motors in both axes that follow celestial objects very precisely.
The handbox with GoTo works reliable and controls the mount in every situation.
Precise ball bearings in both axes ensures minimal backlash at all nine possible tracking speeds.
The battery pack (12 V) is conveniently fastened to the tripod shelf and takes eight size "D" batteries.
The mount rests on a very tough and rigid steel tripod and can take optical tubes of up to 13 kg. GOTO Stargazing at the push of a button!
The Startracker GoTo System enables beginners to start astronomical observations in just a few minutes, and guides you to objects that are hard to localize through a standard finder scope.
Just push the button and the GoTo System will find planets, nebulae or galaxies for you and position your telescope automatically and precise.
The GoTo System database includes thousands of astronomical objects.
The Messier mount with GoTo System allows you to observe without tedious searching, or image faint objects that are hard to find in a standard finder scope.
