The Bresser Sirius 70/900 AZ Refractor Telescope - 70mm is a beginner friendly, high magnification Achromatic Refractor Telescope, with 70 mm aperture, 900 mm focal length, azimuthal mount, tripod, and a wide range of accessories for fascinating discoveries. The telescope features a 90 degree eyepiece to allow you to have the ultimate comfortable viewing experience. This complete astronomy set already includes everything you need to start observing the sky.

This easy to use telescope is ideal for beginners or children to see the wonders of the universe. It has crisp clear imaging, due to multicoated optics and the 70mm aperture, which collects about 100 times more light than the human eye. The resolution of the 70 mm lens lets you enjoy really sharp images at magnifications up to about 140x. This telescope technically can go up to 675x magnification with all the included accessories, however, the more you zoom, the less crisp and clear the view becomes. Due to the long focal length, especially the sun, moon, planets, open star clusters and globular clusters become absolute eye-catchers.

The Sirius telescope comes with everything you need for a quick start in stargazing, see the accessories list below. When searching for celestial bodies worth seeing, take your first look through the included LED viewfinder, it will help you align the telescope precisely for the best view possible. The two eyepieces included in the set (4 mm, 20 mm) allow you to admire completely different views of the same celestial object. More impressively, the 3x magnification Barlow Lens allows you to triple the magnification of the telescope.

Arguably, the most important accessory is the smartphone camera adapter, which allows you to take your first steps into astrophotography, allowing you to use your phone camera to capture the night sky.
