During the summer of 2021, I worked under the solar radioastronomy group in Ondrejov developing code for pointing the 7.5-m RT2 telescope. Up to this point, the telescope was used only during the day for solar observations, and the program for pointing the telescope was hard-coded to always point at the Sun. My task was to produce a generalized astropy-based program, allowing users to point the telescope at a general point in the sky, automatically search for solar system bodies via the JPL-Horizons system or to observe any (deep-sky) object recognizable by SIMBAD.
I continued my work on RT2 in 2023, writing software for reduction and visualization of radio spectra. I also performed many observations, both day time and nigh time, i.e. of the Sun, quasars, pulsars and other radio sources, to further test the newly installed spectrograph.
The RT2 radio telescope in Ondrejov today. It is equipped with a new radio spectrograph, operating in the range 1 GHz - 2 GHz, with a resolution of 1 MHz and a temporal resolution of 1 ms.

This Ondřejov 10-m radio telescope utilises a similar pointing system.
Due to the frequency band (1 - 2 GHz), RT2 can observe in all weather.
