Description
Observe faint nebulae and star clusters with the Omegon Advanced 130/650 EQ-320 Telescope parabolic Newtonian reflector system. Designed in Germany, this fast f/5 telescope features a 130mm (5.12 inches) aperture and a 650mm focal length. The Omegon Advanced 130/650 provides 0.89 arcsecond Dawes resolving power and reaches a limiting visual magnitude of 12.4 for deep-sky stargazers.
The Omegon Advanced 130/650 EQ-320 Telescope utilizes a precision parabolic primary mirror on standard BK7 optical glass, paired with a multi-layer aluminum coating and silicon dioxide top coat. Its roll-formed heavy-gauge steel tube features cast aluminum cell framework end rings and rear collimation screws. Supported by an EQ-320 equatorial mount and steel tripod, the complete assembly weighs 9.80 kg (21.61 lbs), with the optical tube weighing 3.40 kg.
Key Features of Omegon Advanced 130/650 EQ-320 Telescope
Engineered for deep-sky exploration and wide-field observing sweeps, this Omegon Advanced 130/650 Newtonian reflector combines a fast parabolic mirror with an EQ-320 equatorial mount. Its backlash-free Crayford focuser and steel tripod deliver bright, sharp views across Messier objects and rich star fields.
- 130mm (5.12 inches) aperture paired with 650mm focal length and fast f/5 speed
- Precision parabolic primary mirror substrate made from standard BK7 optical glass
- High-reflectivity multi-layer aluminum coatings with protective silicon dioxide layer
- 41mm planar secondary mirror obstruction (31.54% diameter, 9.95% area)
- 1.25-inch Crayford precision friction drive focuser for backlash-free adjustment
- EQ-320 German equatorial mount with balancing counterweight elements
- Adjustable steel tripod with accessory tray and manual slow-motion tracking knobs
- 6×30 optical crosshair finder telescope fitted on fixed support bracket
Parabolic Primary Mirror & Crayford Focuser
The precision parabolic mirror focuses light rays to a single point, eliminating spherical aberration across wide fields of view. Fitted with a smooth 1.25-inch Crayford friction drive focuser, this Omegon reflector supports useful visual magnifications from 18x up to 260x.
EQ-320 Equatorial Mount & Steel Tripod Platform
Tracking deep-sky objects requires rigid equatorial mechanics. The Omegon Advanced 130/650 EQ-320 features an EQ-320 mount head mounted on an adjustable tubular steel tripod to minimize vibrations. Equipped with manual slow-motion tracking knobs and balancing counterweights, it allows astronomers to follow celestial objects across the sky with ease.
- Sturdy EQ-320 equatorial mount with counterweights and slow-motion control knobs
- 1.25-inch Crayford friction drive focuser ensuring smooth, backlash-free focusing
- Kellner 20mm and Kellner 10mm eyepieces paired with a 6×30 optical finder scope
Omegon Advanced 130/650 Warranty
Designed in Germany, the Omegon Advanced 130/650 EQ-320 Telescope comes backed by a 2-year limited warranty against manufacturing defects. The complete package contains the 130mm parabolic Newtonian OTA, EQ-320 mount, adjustable steel tripod with accessory tray, counterweights, slow-motion knobs, 6×30 finder scope, and two Kellner eyepieces.
