Product description

The advantages at a glance:

  • Bright and clear images: The 90 mm aperture collects 25% more light than an 80 mm telescope, allowing you to see even fainter celestial objects.
  • For sky and earth: You see an upright and non-reversed image. This means you can also use the telescope during the day for the observation of nature.
  • Smooth focusing: You can focus the image easily and accurately. Nothing wobbles or slips.
  • Compact and travel-friendly: The telescope is particularly short and light. You can easily take it with you, for example to places with dark skies.
  • Suitable for photography: Take your first moon photos with the smartphone adapter or use an SLR camera for great shots.

More light, more to see: the 90 mm optics
The size of the aperture is crucial for telescopes. With a diameter of 90 mm, this telescope collects significantly more light than typical entry-level telescopes. The result: you see the planets brighter and with more detail. You can also discover objects far beyond our solar system. Discover bright globular clusters that look like small cosmic snowballs. Or recognise the delicate shapes of gas nebulae, such as the famous Orion Nebula.

A walk through the Milky Way: the large field of view
The short focal length of 650 mm provides a large field of view. This means you can see a wide section of the sky. It's like looking at the sky through a wide-angle window. This allows you to explore the Milky Way and see extensive star clusters in their entirety with low magnification. Observing with this wide view is particularly impressive and relaxing.

Precision you can feel: the patented Crayford focuser
A good image is of little use if you cannot focus it accurately. That is why the Omegon AC 90/650 has a high-quality focusing mechanism. Simple instruments often jerk and jolt. This focuser glides smoothly on ball bearings. This allows you to focus the image very finely and accurately. You get very sharp images even at high magnifications: a difference you can feel with every observation.

More than just stars: also ideal for nature observation
With the included amici prism, your telescope becomes a powerful spotting scope for observing the Earth. Unlike with standard astronomical telescopes, you see an upright and non-inverted image. This allows you to observe birds in trees, shy wildlife at the edge of the forest or distant mountain peaks during the day. This makes the telescope a versatile companion for anyone who wants to discover the world: day and night.

Omegon Accessory Box: What good is the best telescope without the right accessories?
With the Omegon accessory box, you get a coordinated set of equipment that makes getting started as easy as possible. Instead of laboriously searching for individual eyepieces and adaptors, you get everything you need for your first observations and even your first moon photos. And all in a quality that exceeds the standard. What do you need to get started? Something that will allow you to make impressive observations right away. This includes two eyepieces for low and medium magnifications. Sometimes you want to get even closer to the action. That's exactly what the included 2x barlow lens is for. It simply plugs between the eyepiece and the telescope and doubles the magnification of the respective eyepiece. An LED finder is extremely important for quickly searching for and finding objects. A red glowing dot in the darkness shows you exactly where to look. You will soon realise that this inconspicuous component is just as important as your telescope. And with the extension tube, you can always find the right focus level.

Your smartphone becomes an astro camera
Perhaps the most exciting part of the accessory set is the smartphone adapter. It allows you to attach your own mobile phone directly to the eyepiece and take photos of what you are observing. Capture the cratered landscapes of the Moon or photograph Jupiter and its moons. The included Bluetooth remote shutter release ensures blur-free images. Share your fascination with the starry sky with your family and friends. It couldn't be easier.
