Description
Sparing real physical effort, the Bresser AC 152/1200 Messier Hexafoc EXOS-2 GoTo shares the high-load platform built for this catalog’s largest common tube, now with dual-axis motorized tracking — genuinely useful at 11.1kg, where manually wrangling slow-motion controls on a tube this size throughout a session is real physical effort.
An illuminated 8×50 finder simplifies alignment in the dark, and an additional balancing weight beyond the standard counterweights accounts for this tube’s substantial mass once an eyepiece or camera is attached. Running the motorized system draws power from 8x D-cell batteries or an optional AC-DC adapter, a practical trade for anyone unwilling to manually manage a tube this heavy through a full evening.
Key Features of Bresser AC 152/1200 Messier Hexafoc EXOS-2 GoTo
A dual-axis motorized StarTracker system on the high-load EXOS-2 platform automates tracking for this catalog’s largest common achromat, removing real physical strain from a long session.
- Dual-axis motorized tracking follows targets automatically once aligned
- Additional balancing weight accounts for this tube’s substantial mass with accessories
- 8×50 illuminated finder scope simplifies alignment on dimmer targets
- Runs on 8x D-cell batteries or an optional AC-DC adapter
- Hand controller’s database locates catalogued deep-sky targets directly
- High-load platform carries this tube with genuine payload margin
- Motorized tracking spares an observer from manually wrangling this heavy tube
How the EXOS-2 GoTo Compares
Against the manual EXOS-2 sharing this mount platform, the GoTo version’s motorized tracking matters more here than on lighter tubes — manually managing an 11.1kg tube’s slow-motion controls throughout a long session is real effort the motorized system removes entirely.
Applications & Use Cases
Built for advanced motorized GoTo tracking, this telescope handles high-aperture high-resolution tracking of lunar surfaces, fine planetary structures, and deep-sky observation across an extended session.
- Advanced observers wanting automated tracking on serious aperture
- Anyone who’d rather not manually wrangle an 11.1kg tube’s controls
- Buyers who’d rather manage batteries than fight a heavy tube by hand
Bresser Warranty & Support
The AR-152L/1200 EXOS-2 GoTo carries a 2-Year Factory Warranty covering manufacturing defects, handled directly through Bresser’s support channel.
