f/8 contrast on the heavier EXOS-2 mount!
The Bresser Messier 150/1200 Hexafoc EXOS-2 uses the f/8 planet lens on the heavier EXOS-2. The long tube requires stability, and this EQ-5 class mount provides plenty of it. The included objective-sun filter also allows for safe solar observations.


f/8 optics with Hexafoc
The 150 mm parabolic mirror captures about 459 times more light than the naked eye. The long focal length of 1200 mm (f/8) provides high contrast at high magnification: exactly what you want for the Moon, planets, and double stars. With the 26 mm Super Plössl eyepiece, you’ll achieve 46x magnification; stick to approximately 300x as the maximum. The 2.5-inch Hexafoc focuser with adapters provides stable support even for heavy eyepieces. Use the solar filter only if it is undamaged, and never look at the Sun without certified protection.
The EXOS-2 mount
The EXOS-2 is a German equatorial mount of the EQ-5 class with a payload capacity of up to 13 kg. With the polar finder scope, you can align quickly, and with the slow-motion cables, you can track objects smoothly. If you want automatic tracking later, the mount can be expanded with a motor set or the complete StarTracker GoTo system.
