Omegon Telescope Horizon AC 90/650 (87240)

The AC 90/650 is a powerful and versatile telescope designed for impressive observations of both the night sky and nature. It is especially well suited for exploring the solar system, as its 90 mm aperture gathers enough light to reveal detailed views of the Moon and planets. Bright nebulae and star clusters are also within reach, making it an excellent choice for beginners who want to actively explore the sky.

Key Advantages at a Glance

• Bright, clear images thanks to a 90 mm aperture that collects 25% more light than an 80 mm telescope

• Suitable for sky and daytime observation with an upright, correctly oriented image

• Smooth and precise focusing without wobble

• Compact and lightweight design for easy transport to dark-sky locations

• Ready for photography with a smartphone adapter or SLR camera

More Light, More Detail: 90 mm Optics

A larger aperture significantly improves what you can see. With a 90 mm diameter, this telescope gathers noticeably more light than smaller beginner models. Planets appear brighter and show finer details. You can also observe objects beyond our solar system, such as bright globular clusters and delicate nebulae like the Orion Nebula.

Wide Field of View for Relaxed Observing

The 650 mm focal length provides a wide field of view, allowing you to observe large sections of the sky at once. This makes it ideal for exploring the Milky Way and viewing extensive star clusters at low magnification. The wide perspective creates an immersive and enjoyable observing experience.

Smooth Precision with the Crayford Focuser

Accurate focusing is essential for sharp images. The high-quality Crayford focuser operates smoothly on ball bearings, enabling fine and precise adjustments without slipping. Even at higher magnifications, achieving crisp focus is easy and reliable.

Ideal for Nature Observation

With the included 90° Amici prism, the telescope produces an upright, non-reversed image. This makes it suitable for daytime use as a spotting scope. Observe birds, wildlife, or distant landscapes with clarity, making the telescope a versatile companion for both day and night exploration.

Complete Accessory Package for Immediate Use

The included accessory set ensures you can begin observing right away. Two Plössl eyepieces provide low and medium magnifications. The 2x Barlow lens doubles the magnification when placed between the telescope and eyepiece.

An LED red dot finder with adjustable brightness helps you quickly locate objects in the sky. The extension tube allows you to achieve the proper focus position when required.

Turn Your Smartphone into an Astro Camera

The smartphone adapter allows you to attach your mobile phone directly to the eyepiece and capture images of your observations. Photograph detailed lunar landscapes or Jupiter and its moons. The Bluetooth remote shutter release reduces vibration for sharper results and makes sharing your discoveries simple.
