The Bresser Sirius achromatic refractor is already larger than the one used by Galileo Galilei many years gone past. Yet not only its magnification power is larger but also the quality of the optics used has increased by many times. Beginners will especially find the altazimuth mount beneficiary as it easily lets them move around the sky at night. The included astro software lets you compare what you see on your monitor with the night sky.
