Cassiopeia A it’s an important object for radio astronomy, a supernova remnant located in Cassiopeia constellation with a flux of 2400 Jansky at 1420 MHz. For this article we used the SPIDER 300A radio telescope that, thanks to the 3 meter parabolic antenna with high precision WP-100 mount, high sensitivity H142-One receiver, and the advanced features of the RadioUniversePRO software, is able to detect Cassiopeia A. The radio telescope is connected to the remote control room by using the Radio over fiber kit for SPIDER radio telescope that removes the normal gain loss because of cable length and improve even more performances of the radio telescope.

The Sun is one of the most interesting radio sources in the sky and solar radio emission can be studied by using SPIDER radio telescopes. The Sun not only emits visible light but also other frequencies in the electromagnetic spectrum, in fact you can feel the Sun heat on our skin, expression of infrared radiation. In this article with step-by-step guide, by using a 3 meter diameter SPIDER 300A radio telescope, we see how to detect radio waves coming from the Sun and generate various results (like radio images and transits) by using the RadioUniversePRO control software. We perform automatic pointing and tracking on the Sun, detection and removal of eventual artificial signal and capture of results.
