This device is a very nice and exceptionally well-crafted beginner telescope. The high quality of the optical elements used provides an unusually sharp and high-contrast image for this class of telescope. The fixed red dot finder allows for quick and easy locating of desired targets. You can easily adjust the focus using the 1.25" rack and pinion focuser. The telescope is suitable for both nature and terrestrial observation, as well as for astronomical applications such as observing the moon and planets. The tube is mounted on a standard dovetail rail on the mount. The device can be fully set up in just a few minutes without any special knowledge or tools.
