Description
Track stellar configurations and deep-space objects with minimal vibration decay using the Omegon N 126/920 EQ-3 Telescope manual equatorial Newtonian reflector system. Designed in Germany, this f/7.3 telescope features a 126mm (4.96 inches) aperture and a 920mm focal length, delivering 0.92 arcsecond Dawes resolving power and reaching magnitude 12.3 for stargazers.
The Omegon N 126/920 EQ-3 Telescope utilizes a spherical BK7 optical glass primary mirror treated with standard aluminum coatings and a protective monoxide overlay. Its roll-formed heavy-gauge steel tube features cast aluminum cell end rings and rear collimation retention screws. Supported by a robust EQ-3 equatorial mount on an adjustable aluminum tripod, the complete setup weighs 11.20 kg (24.69 lbs), while the 160mm by 880mm optical tube weighs 3.40 kg.
Key Features of Omegon N 126/920 EQ-3 Telescope
Engineered for deep-space tracking and planetary viewing, this Omegon N 126/920 Newtonian reflector telescope pairs a 126mm aperture with a heavy-duty EQ-3 equatorial mount. Its rigid dovetail mounting and dual slow-motion cables deliver steady, sharp views across binary star systems and nebulae.
- 126mm (4.96 inches) aperture with 920mm focal length and versatile f/7.3 focal ratio
- Spherical primary mirror substrate made from standard BK7 optical glass
- Standard aluminum optical coatings with protective monoxide overlay layer
- 34mm planar secondary mirror obstruction (26.98% diameter, 7.28% area)
- 1.25-inch rack and pinion focuser with manual tension adjustment screw
- Heavy-duty EQ-3 precision equatorial mount head with heavy balance weights
- Hinged tube ring array fixed to a Vixen-style dovetail mounting bar
- 6×30 optical crosshair finder telescope fitted on fixed support bracket
Mid-Aperture Newtonian Optics & Low Vibration Chassis
The 126mm primary mirror gathers generous light across an f/7.3 focal layout, delivering high-contrast images of moon craters, Saturn, and bright star clusters. Equipped with a 1.25-inch rack and pinion focuser, this Omegon telescope supports visual magnifications from 18x up to 252x.
EQ-3 Equatorial Mount & Heavy Balance System
Observing fine celestial details requires a rigid equatorial platform that dampens vibrations quickly. The Omegon N 126/920 EQ-3 features an EQ-3 mount head with heavy counterbalance weights and slow-motion tracking cables. Supported by an adjustable aluminum tripod, it allows astronomers to follow deep-sky objects smoothly across right ascension and declination axes.
- Heavy-duty EQ-3 equatorial mount with heavy counterweights and tripod accessory tray
- Flexible slow-motion tracking cables for smooth manual celestial tracking
- Included 1.25-inch Kellner 25mm and Kellner 10mm eyepieces with a 6×30 finder scope
Omegon N 126/920 EQ-3 Warranty
The Omegon N 126/920 EQ-3 Telescope is backed by a 2-year limited warranty covering parts and craftsmanship defects. The complete package contains the 126mm spherical Newtonian OTA, EQ-3 mount head, adjustable aluminum tripod with accessory tray, heavy balance weights, slow-motion cables, 6×30 finder scope, and two Kellner eyepieces.
