FAQ - Frequently Asked Questions

Why do I see everything upside down and mirrored in the finder?

That is normal. Finder scopes are only used to make objects easy to locate. The image orientation does not matter for observation.

What is the difference between an alt-azimuth mount and an equatorial mount?

Alt-azimuth: easy to use, moves horizontally and vertically
Equatorial: enables precise tracking of objects with only one axis – ideal for high magnifications and astrophotography

What minimum apertures do I need for certain objects?

Moon: from 30 mm
Planets: from 100 mm
Deep sky: from 150 mm

Product information "BRESSER Refractor 90/500 EQ3 Telescope"

NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.

Excellent for entering into the hobby of astronomy: 90mm aperture delivers 200 times more light than the naked eye! Observe craters, valleys and rims on the Moon from nearly 400,000km away, just as you would look out of the window of a spaceship!

The BRESSER AR-90s with EQ-3 mount does not only provide highly detailed views of the moon: Gaze at the division of the rings of Saturn millions of kilometres away, or explore the Great Red Spot of Jupiter, a giant tornado in Jupiter's atmosphere. Watch the seasons on Mars and find the sickle of Venus.

Richfield telescope with a short focal length of 500mm. Suitable for traveling and to observe large open star clusters and the milky way.

The BRESSER AR-90s gives you images that are many times brighter than the instrument Galileo Galilei was using for his famous explorations almost 400 years ago.

This telescope is mounted on a very stable German Equatorial EQ-3 Mount which offers a very easy and precise manual tracking of the celestial objects.
