Omegon AC 80/400 Telescope -. Wide image so you see more of the world
The Omegon AC 80/400 Telescope is a compact telescope for those who like to see a lot at once. You not only look up at the stars, but also over land and sea. One telescope, two worlds. That makes it versatile and fun to use.
80 mm aperture, for clear and calm images
The 80 mm lens captures enough light to show objects clearly. That means a quiet viewing experience with clear details. Ideal for wide star fields, open star clusters and bright objects such as the Moon.

Short focal length, so an extra-large field of view
Thanks to the short focal length of 400 mm, you can see a large chunk of the sky at once. Perfect for ‘walking’ along star fields. You see connections between objects and get oriented to the sky faster.
Rich-field telescope, made for exploring
This telescope lets you enjoy overview rather than extreme magnification. Think of the Andromeda galaxy fitting nicely into view, or large open star clusters really coming into their own. Thus, observing feels relaxed and natural.
Also suitable for daytime nature observation
Don't use your telescope only at night. During the day, you can just as easily look at landscapes, animals or ships in the distance. That makes this telescope ideal if you love being outdoors and want one instrument for everything.

Multicoating so your image stays clear
The lenses have a multiple coating that reduces reflections. This keeps your image clear and rich in contrast. You see more details without distracting glare.
Light and sturdy, easy to assemble
The aluminum tube is light but stable. Weighing only 1.3 kg, you can easily take it with you. You easily mount it on a suitable mount or tripod, just the way you want.
