If you are dreaming of getting your first-ever telescope or looking for a gift for a beginner astronomer, check out the Discovery Spark 707 AZ Telescope with a book. It combines everything that you might need for the first glimpse at the night sky: easy controls, a wide range of astronomical observations, and an extended kit of accessories. You can observe the details of lunar landscapes, the planets of the Earth group, and even distantly see the brightest deep-sky objects. It is also possible to explore terrestrial objects during the day using the telescope as a spotting scope.
The Discovery Spark 707 AZ is based on the achromatic refractor scheme, i.e., the image forms without color distortion. The outer surfaces of the glass lenses have an anti-reflective coating: It helps the system gather more light, which ensures high picture quality over the entire FOV. The alt-azimuth mount is easy to master, and the vertical axis is equipped with a lock knob for precise adjustment. The rack and pinion focuser adjusts the focusing. Thanks to its standard 1.25" diameter, the telescope is compatible with many optical accessories.
The height of the aluminum tripod legs is adjustable, and the accessory tray keeps the accessories always on hand. The kit comes with three eyepieces, providing different magnifications, an erect image eyepiece, and a 3x Barlow lens. In addition to the device and its accessories, you will find the book of knowledge “Space. Non-Empty Emptiness” in a colorful box. The book provides a detailed description of the celestial bodies of the solar system, which is particularly interesting for the refractor owners, and also gives practical advice on the process of telescopic observation.
