The International 3621138C2 Reflector Prostar is a high-performance reflective telescope designed for astronomers and stargazers seeking a reliable and efficient tool for observing the night sky. This reflecting telescope boasts an impressive 130mm (5.1 inches) aperture, which gathers a significant amount of light, enabling you to see fainter objects and enjoy brighter, clearer images.

The Reflector Prostar features a Newt nian design, with a parabolic primary mirror and a flat secondary mirror.

The tube length is approximately 1145mm (45.1 inches), making it suitable for transport and storage in a standard-sized case.

The Reflector Prostar includes a 2-inch Crayford-style focuser, which provides 2:1 fine focus and 10:1 coarse focus. This focuser supports a wide range of eyepieces and accessories, enabling you to explore various aspects of the night sky in detail. Additionally, the telescope comes with a Vixen-style dovetail mounting plate, allowing for easy attachment to mounts and tripods.

The telescope also includes a 25mm Pl ssl eyepiece, which offers a magnification of 40x, and a 9mm Pl ssl eyepiece, which offers a magnification of 113x. These eyepieces provide a wide and comfortable field of view, making them ideal for observing various celestial objects.

The Reflector Prostar is a versatile and powerful telescope, suitable for both beginner and advanced astronomers. Its large aperture gathers plenty of light, allowing you to explore the depths of the universe, while its high-quality optics deliver sharp and clear images.
