The Discovery Spark Travel 50 telescope with a book is everything a beginner astronomer could possibly dream of. A compact and lightweight device comes with a practical carrying case, tabletop tripod, and other necessary accessories, including the “Space. Non-empty emptiness” knowledge book. Thanks to this colorful entertaining encyclopedia, you can get practical insights about the space objects that are seen through the telescope. The book has a soft cover, so it is easy to take it with you to an astronomy festival or out of town along with the telescope itself and its accessories.
Discovery Spark Travel 50 is designed to observe the Moon and terrestrial objects. According to its optical scheme, it is an achromatic refractor. The optical glass lenses have an anti-reflective coating, which contributes to the reflective properties of the telescope and improves the quality of the picture. The short focal length provides a wide FOV, so you can cover a wide area with a single glance. The telescope tube is mounted on an easy-to-use alt-azimuth mount and moves easily in both azimuth and altitude directions.
