Omegon N 130/920 EQ-2 Newtonian Reflector Telescope

The Omegon N 130/920 EQ-2 is a capable beginner's Newtonian reflector combining a useful 130mm aperture with a long 920mm focal length and an equatorial EQ-2 mount. It provides enough light-gathering power to move beyond the Moon and planets and begin exploring brighter nebulae, star clusters and galaxies.

Its f/7.1 Newtonian optical system makes this an excellent choice for learning traditional visual astronomy, while the equatorial mount introduces the observer to polar alignment and accurate manual tracking of objects across the night sky.

130mm Newtonian Optics – More Light, More to Explore

Aperture makes a major difference to what a telescope can reveal. With a 130mm primary mirror, the Omegon 130/920 gathers substantially more light than smaller beginner instruments such as a 114mm Newtonian.

The supplied specification gives a light-gathering capacity of 350, together with a limiting magnitude of 12.4. This provides enough reach to make many brighter deep-sky objects accessible from suitably dark observing locations.

The 920mm focal length and f/7.1 focal ratio also provide a useful range of magnifications using conventional 1.25-inch eyepieces.

Discover the Moon and Planets

The 130mm aperture provides plenty of potential for exploring the Solar System. The Moon reveals craters, mountain ranges, plains and fine shadow detail, particularly around the lunar terminator.

Jupiter can show its principal atmospheric belts and four bright Galilean moons, while Saturn's ring system is an impressive target. Mars can also reveal detail when it is favourably positioned and observing conditions are suitable.

The formal specification gives a resolving capacity of 0.88 arcseconds and a maximum useful magnification of 260x. Actual usable magnification will depend on atmospheric seeing, optical collimation and the target being observed.

Move Beyond the Solar System

One of the advantages of moving up to a 130mm reflector is the opportunity to explore more deep-sky objects.

Under suitably dark skies, the telescope can be used to observe open and globular star clusters, brighter nebulae and galaxies. Objects such as the Orion Nebula and Ring Nebula provide an introduction to a very different type of astronomy from lunar and planetary observing.

The combination of 130mm aperture and 920mm focal length therefore makes the telescope a versatile first instrument for discovering a broad range of celestial targets.

Collimatable Newtonian Optical System

Correct optical alignment is important if a Newtonian reflector is to perform at its best. The Omegon 130/920 provides collimation adjustment for both the primary and secondary mirrors.

This allows the mirrors to be correctly aligned when required, helping the telescope deliver the sharpest image its optics and observing conditions permit.

1.25-Inch Rack-and-Pinion Focuser

The optical tube is fitted with a conventional 1.25-inch rack-and-pinion focuser, allowing it to accept standard 1.25-inch astronomical eyepieces and compatible filters.

An important detail in the supplied product information is the included focuser extension adaptor. The supplier states that this adaptor is required to achieve focus and allows the focuser to be used with both eyepieces and compatible SLR camera arrangements.

For DSLR connection, the supplied information states that a camera-specific T2 ring is additionally required.

Please note: although a compatible camera can be mechanically attached using the appropriate adaptor arrangement, the formal specification rates astrophotography as not recommended. The EQ-2 version should therefore be regarded primarily as a visual astronomy telescope rather than a dedicated astrophotography setup.

Red Dot Finder for Locating Targets

A red dot finder is included to make pointing the telescope at celestial objects easier. Once correctly aligned with the main optical tube, the illuminated reference point helps you position the telescope before switching to the main eyepiece for closer observation.

EQ-2 Equatorial Mount

The telescope is supplied with an EQ-2 equatorial mount. An equatorial mount is designed around the apparent movement of the night sky and, once correctly polar aligned, allows an object to be followed more naturally as the Earth rotates.

The mount provides fine-motion adjustment in right ascension and declination, allowing small, controlled corrections when centring and tracking an object.

A counterweight balances the optical tube around the mount, helping provide smoother movement during observing.

Learn Polar Alignment and Manual Tracking

The EQ-2 gives a beginner the opportunity to learn the fundamentals of a traditional equatorial telescope mount.

After setting the mount for the observer's geographical latitude and aligning it towards the celestial pole, objects can be tracked using the right ascension axis rather than repeatedly making large adjustments in two directions.

There is no GoTo system on this model, making it particularly suitable for someone who wants to learn the night sky and understand how an equatorial mount works.

Height-Adjustable Aluminium Tripod

The EQ-2 is supported by an extendable aluminium tripod. Its adjustable legs allow the observing height to be altered, while the accessory tray provides convenient storage for eyepieces and other small accessories during an observing session.

25mm and 10mm Eyepieces Included

Two standard 1.25-inch eyepieces are supplied:

• 25mm eyepiece – approximately 37x magnification
• 10mm eyepiece – approximately 92x magnification

These provide useful starting magnifications for locating and observing a variety of celestial objects. Additional compatible 1.25-inch eyepieces can be added later to expand the available magnification range.

A Capable First Telescope for Visual Astronomy

The Omegon N 130/920 EQ-2 is particularly suited to beginners who want more light-gathering capability than a smaller starter telescope while still learning astronomy with a traditional manually operated instrument.

The 130mm Newtonian optics provide access to the Moon, planets and a useful selection of deep-sky objects, while the EQ-2 mount introduces the fundamentals of balancing, polar alignment and celestial tracking.
