Wide image, lots of detail
The Omegon AC 90/650 gives you a quick start in astronomy. You set it down, aim and look. The 90 mm lens shows more detail and makes images look clear and stable. The 650 mm focal length delivers a wide image. Useful for finding objects and seeing the entire Moon at once. The AZ-Bellavista mount moves smoothly and feels instantly familiar.
Clear and high-contrast image
The 90 mm achromatic optics capture a lot of light. f/7.2 keeps the image calm and sharp. Stars remain dots, details stand out. This keeps your image clear and sharp, even when you zoom in a bit further.
Focusing that just works
The Crayford focuser runs on ball bearings. It rotates smoothly and without backlash. You can find the exact focus in seconds. Even at higher magnification, the image remains stable and tight.
AZ-Bellavista: aim and enjoy
Move just like with a good photo tripod: up, down, left and right. With fine adjustment in both axes, you follow each target smoothly and precisely. The stainless steel tripod dampens vibrations. So you keep your target centered without fuss.
For day and night
With the 90° amici prism, you look straight and true to nature. By day, you observe birds and landscapes. At night you switch effortlessly to the Moon and planets. One telescope for two worlds.
Ready to begin
Everything you need is included. An LED viewfinder for quick aiming. Plössl eyepieces of 25 mm and 10 mm for low and medium magnification. A 2x Barlow to get closer. An extender to always get in focus. And a smartphone adapter with Bluetooth shutter for your first lunar photos without vibrations.
What to expect
The Moon shows sharp edges, deep craters and long shadows. Jupiter shows cloud bands and four moons. Saturn appears with distinct rings and sometimes even the Cassini separation in good seeing. The Orion Nebula and Andromeda show up as bright nebulae under dark skies. During the day you can see animals and distant details with a natural, upright image.
What we recommend
✓ Moon: excellent fit
✓ Planets: lots of detail and pleasant magnifications
✓ Nature observation: very suitable with upright image
✗ Deep-sky: limited to bright objects
✗ Astrophotography: not suitable

The manual (which I'm missing) could be clearer and is sometimes difficult for a complete beginner to understand.
