Omegon AC 90/500 Telescope - Quick on the move, seeing more
The Omegon AC 90/500 telescope is made for convenience. You set it up quickly and start looking right away. Its compact size makes it easy to take with you on trips, to the garden or a dark spot outside the city. No heavy equipment. No fuss. Just look.
Clear image with a relaxed viewing experience
The 90 mm lens captures enough light to clearly show the Moon, planets and bright nebulae. Images remain bright and contrasty, so details stand out better. The special coating reduces distracting reflections. That means calmer viewing and seeing more, even at low magnification.

More sky at a glance
The short focal length allows you to see a large part of the sky at once. Ideal for star fields and large nebulae. You need to search less and see immediately where you are looking. This also works nicely in daytime nature and landscape observations.
Focusing feels smooth and precise
The 2″ Crayford focuser turns gently and in a controlled manner. You focus quickly, without jerking. This is especially helpful at higher magnifications, keeping your image steady and sharp. Use wide eyepieces for a wide image or easily switch to 1.25″.
Sturdy build, made to take with you
The metal tube feels solid and can withstand heavy use. The retractable dew cap protects the lens from moisture and stray light. This keeps your image clear, even during longer observing sessions.
Compact mount, intuitive to use
The included Baby AZ mount moves smoothly in all directions. You follow objects easily by hand. Even at higher magnification, it remains pleasant to work with. The mount is light, but stable. Perfect for quick and spontaneous observations.

Light tripod, surprisingly stable
The carbon tripod is easy to carry yet sturdy. You set it low or high, depending on what you are comfortable with. When folded, it fits into almost any bag. Ideal for travel and mobile use.
Why this telescope suits you
You want a telescope you use more often because it's always ready to go. The Omegon AC 90/500 gives you clear images, great overview and maximum flexibility. For beginners who want quick results and for advanced users who want to travel light.
