The Discovery Spark 703 AZ telescope with a book is a compact short-focus refractor on a tabletop tripod. It is perfect for observing the night sky from a windowsill or balcony. It is also suitable for travel as it will not take up much space. You can view the Moon, the planets of the Earth group, and terrestrial objects. In the daytime, the telescope can serve as a spotting scope. All of the necessary accessories are already included.
The telescope is an achromatic refractor: color distortions, which are typical for refracting telescopes, are well compensated. The optical elements are made of glass with an anti-reflective coating, which significantly improves the clarity and sharpness of an image. The telescope tube is installed on an alt-azimuth mount with a convenient focusing knob, so even an amateur astronomer without prior experience can master the controls. The compact tripod is made of aluminum and designed to be placed on a table, windowsill, or any other surface.
Discovery Spark 703 AZ comes with accessories that may fully unleash the potential of the optical device: three eyepieces (including an erect image eyepiece), a Barlow lens, and a diagonal mirror. The colorful “Space. Non-empty emptiness” knowledge book will provide many fascinating facts about space and its exploration and become your personal guide through the solar system.
