Bresser AC 127S/635 Messier EXOS 2 GoTo

Description

Freeing both hands for observing, the Bresser AC 127S/635 Messier EXOS 2 GoTo removes the effort of manually chasing a comet across a wide field while also managing a 7.7kg tube’s slow-motion controls by hand, adding dual-axis motorized tracking to the same high-load platform as the manual EXOS-2 version.

An illuminated 8×50 finder simplifies alignment in the dark, and once tracking, the motorized system handles this tube’s wide field automatically — freeing both hands for actually observing rather than nudging controls throughout a session. Running the motorized system draws power from 8x D-cell batteries or an optional AC-DC adapter, a real consideration for anyone planning a long night far from an outlet.

Key Features of Bresser AC 127S/635 Messier EXOS 2 GoTo

A dual-axis motorized StarTracker system on the same high-load EXOS-2 platform automates wide-field tracking for this line’s heaviest rich-field tube, removing the physical effort a manual mount demands.

• Dual-axis motorized tracking follows wide-field targets automatically once aligned
• High-load platform carries this catalog’s heaviest tube with real payload margin
• 8×50 illuminated finder scope simplifies alignment on dim comet targets
• Two included 4.5kg counterweights balance heavier accessory loads
• Runs on 8x D-cell batteries or an optional AC-DC adapter
• Hand controller’s database locates catalogued deep-sky fields directly
• Motorized tracking removes the physical strain of manually wrangling a heavy tube

How the EXOS 2 GoTo Compares

Against the manual EXOS-2 sharing this mount platform, the GoTo version’s automated tracking is a genuine convenience specifically because this tube is heavy enough that manual slow-motion adjustments take real effort during a long session — motorized tracking frees you to actually look rather than constantly nudge controls.

Applications & Use Cases

Built for automated motorized object finding, this telescope suits rich-field deep-sky exploration, comet surveys, and low-magnification imaging fields across an extended session.

• Comet-watchers who want automated tracking on a serious-aperture rich-field scope
• Observers who’d rather not manually wrangle a 7.7kg tube’s slow-motion controls
• Anyone running long sessions where hand fatigue becomes a real factor
