SPIDER 230C compact radio telescope, kit without mount


SPIDER 230C is the compact radio telescope that combines radio with amateur astronomy technologies that will allow you discover the world of radio astronomy with a powerful, modular and easy-to-use product! We developed this radio telescope to allow everyone to approach this fascinating science with an affordable, turn-key, high-performance instrument.

Thanks to our patented technology, SPIDER 230C lets you use an equatorial mount (not included in this kit, must be added separately) with at least 50 Kg payload capacity, by creating a compact radio telescope for 1420 MHz radio astronomy!

SPIDER 230C compact radio telescope, kit without mount

The SPIDER 230C compact radio telescope uses the WEB230-5 antenna, a mesh 2.3-meter diameter parabolic antenna designed to offer a larger diameter with lower overall weight. The 230C weighs much less than a normal 1.5 meter diameter full-surface model, offering better resolution capacity due to its greater diameter while maintaining a lower sensitivity to wind due to the perforated surface of the antenna. The reflecting surface of this antenna (the primary reflector) is composed of an aluminum mesh with 3×4 mm holes for optimum reflectivity of radio waves with frequencies up to 5 GHz.
