Celestron Telescope AC 90/1000 Astromaster AZ

Celestron Telescope AC 90/1000 Astromaster AZ is a powerful refractor for beginners and hobby astronomers who want to see more detail than with a 70 mm telescope. Thanks to its 90 mm aperture, it captures almost 70% more light, rendering objects brighter and more contrasty. The long focal length of 1000 mm makes this instrument particularly suitable for lunar and planetary observations.

The f/11 optics deliver sharp and color-fast images. Thus, you not only see the craters and mountains on the moon in detail, but also the cloud bands and moons around Jupiter, the rings of Saturn and the phase of Venus. Bright deep-sky objects such as the Orion Nebula or the Pleiades are also visible.

The telescope stands on a sturdy azimuthal mount with a robust tripod that offers low-vibration operation. The red dot finder makes it easy to point the telescope at your target, while the 1.25″ focuser allows you to focus accurately. Within minutes, the telescope is set up and ready to use without tools.

Application
The Celestron AC 90/1000 Astromaster AZ is ideal for:

• Moon: detailed crater landscape and shading.
• Planets: Saturn with rings, Jupiter with cloud bands and moons, Mars during opposition.
• Deep-sky: Orion Nebula, Pleiades and other bright star clusters.
• Nature and earth observation: with an Amici prism also usable during the day.

For astrophotography, this model is of limited use, suitable for simple snapshots of the moon with a smartphone adapter.
