The Omegon 130/920 EQ-3 telescope is just the right telescope for taking your first steps in exploring the night sky. With a very high light collection capacity it is an easy matter to undertake excursions into the world of deep-sky objects. Whether it is Saturn with its ring systems, or the Ring Nebula 2300 light years away with its diaphanous ring - with the Omegon 130/920 even more is possible!
Optics and tube
The 130-mm aperture actually offers 30% more light collection capacity than the smaller 114/900-mm model. The optics collect 344 times more light than the naked eye. These figures give an idea of what this telescope size is capable of. The actual magnification is often not the most important factor in observation; however, under favourable conditions, with suitable eyepieces, a maximum effective magnification of up to 260 times can be achieved. The resolution and magnification suffice for distinguishing the larger features on some planet surfaces. The barrel is equipped with a 1.25″ focuser into which all standard eyepieces can be fitted.
The Omegon 130/920 is mounted on a parallactic EQ-3 mount. With a parallactic carriage, it is always possible to keep a heavenly body in the middle of the field of vision. To this end, the EQ-3 mount is aligned with the Pole Star, which is always due North, before the start of observations. The carriage has two axes (declination and right ascension) that are of vital importance for aligning the telescope with heavenly bodies. Once an object has been centered, it can always be maintained in this position with the integrated fine adjustment mechanism.
The EQ-3 mount is significantly more stable than the smaller EQ-2 mount. This means that the optics are considerably less susceptible to vibrations and shaking. The longer-than-average barrel is held more securely and increased enjoyment from your observations is guaranteed.
This combination of optics and carriage is highly suitable for visual observations and for the first attempts at astrophotography. The aluminium tripod provides the stable base which is the absolute prerequisite for high quality observations. A practical eyepiece tray, which is always useful for accessories or celestial charts, can be attached between the tripod legs. The tripod itself can be adjusted to any height in the range 72 - 124 cm, so that all astronomers, young or old, are always assured of an optimum view.
The 130/920 Optics
The 130mm aperture offers around 30% more light gathering capacity than the smaller 114/900mm model and the optics collect 344 times more light compared to the naked eye. These figures show that this size of telescope already has a host of possibilities.
It is not always possible to use the highest magnification when observing, but, under good conditions and with a suitable eyepiece, magnifications of up to 260 times are feasible. The resolution and magnifications possible are already sufficient to get to know the initial features on some planets. The tube has a 1.25” focuser, which can take all the standard eyepieces.
If you then want to observe outside the solar system too, numerous objects such as star clusters, hydrogen nebulae and even some galaxies will be opened up to you.
Would you also like to try your hand at photography? Here too you can take the first steps. With just a simple digital camera and an optional camera adapter you will already be able to take attractive shots of the moon.
The Omegon N130/920 Newtonian telescope is simple to collimate. This is important, because only when well collimated will the telescope be able to boast its full performance. There are adjustment screws for collimation for the secondary and main mirrors.
The advantages in a nutshell:
The EQ-3 mount:
This parallactic mount allows you to accurately aligning the optics to the Pole Star. The correct polar height and geographical latitude can be set for any observation location. The slow motion controls for the RA and DEC axes allow objects to be adjusted precisely, tracked and held in the field of view. A counterweight provides exact counterbalancing of the optics.
The EQ-3 mount provides a solid base for most small to medium size optics and is excellent for fascinating excursions through the night sky. Drive motors are available for automatically guiding the EQ-3 mount, which also allows any first attempts at astrophotography. The tripod is extendable, an accessory tray provides a place for eyepieces and other accessories.
