Description
Eliminating vibration at maximum magnification, the Bresser MC 152/1900 Messier Hexafoc EXOS-2 GoTo shares the same 152mm Maksutov as every other version in this line, now on the EXOS-2 GoTo platform: dual-axis motorized tracking that holds a target centered at up to 304x without a hand on the slow-motion controls.
At this focal ratio and magnification, a planet drifts out of frame within moments without active tracking — motorized GoTo directly solves that, and the ultra-stable platform eliminates the vibration a tube this size could otherwise introduce at high power. Power comes from 8x D-cell batteries or an optional AC-DC adapter, and the illuminated finder scope makes the initial alignment considerably easier once true darkness sets in.
Key Features of Bresser MC 152/1900 Messier Hexafoc EXOS-2 GoTo
Dual-axis motorized tracking on an ultra-stable platform eliminates vibration at this tube’s highest-in-catalog magnifications, solving a limitation manual mounts handle less gracefully at this power.
- Dual-axis motorized tracking holds targets centered at up to 304x
- Ultra-stable platform eliminates vibration this tube’s high power could otherwise show
- Hand controller’s database locates catalogued targets without star-hopping
- Two included 4.5kg counterweights balance the 6.5kg tube’s mass
- Runs on 8x D-cell batteries or an optional AC-DC adapter
- External Hexafoc focuser adds fine control most compact Maksutovs skip
- Continuous tracking keeps a target framed at this catalog’s highest magnification
Why Choose the EXOS-2 GoTo
Against the manual EXOS-1 sharing this tube’s optics, motorized tracking matters most here specifically because this is the highest-magnification Maksutov in the catalog — a drifting target is more disruptive at 304x than at any lower power this line offers.
Applications & Use Cases
Built for automated GoTo target location, this telescope delivers motorized tracking for high-magnification planetary observation, eliminating vibration on this high-resolution 6-inch configuration.
- Planetary observers running this catalog’s highest-magnification sessions
- Anyone who wants automated tracking at the top of this catalog’s Maksutov range
- Observers who’d rather manage batteries than manually track at 304x
Bresser Warranty & Support
The MC-152/1900 EXOS-2 GoTo carries a 2-Year Factory Warranty covering manufacturing defects, handled directly through Bresser’s support channel.
