Bresser Arcturus 60х700 (17803)

Small Bresser Arcturus 60/700 achromatic refractor is perfect for a beginner as it is easy to use, no prior experience needed. In addition, it is installed on a simple Alt-Azimuth mount that does not require any adjustment before observations, and is equipped with a micrometer-screw on the vertical axis for more convenient tracking. This telescope will let observers see lunar craters and Jupiter's satellites, Saturn's rings, and many other interesting objects. A special erecting lens giving a direct image of observed objects allows you to use this telescope as a powerful spotting scope for terrestrial observations.
The telescope features f/11.7 focal ratio and high-quality coated glass that ensures great color rendering properties and reduces the effect of chromatic aberrations.
The device is equipped with a focuser that has a standard barrel diameter of 1.25", which allows installing accessories of other manufacturers. The basic kit provides magnification in the 35–262x range.
The telescope comes with a practical, hard carry case. You can use the case for storing the microscope and all accessories and keeping it dust-free, and for transporting your instrument without risk of mechanical damage. It has small dimensions, so you will be able to get to your observing spot using public transportation.
