hello i would like to ask if there are small radio telescopes that can image stars, galaxies, and universes similar to the larger radio telescopes. thanks very much.

Yes but the better ones are not cheap however here is a couple of affordable models

Some of the above are kits which seems to be more common to build your own rather than purchase one.

Some early radio telescopes were built by amateurs, though they were very dedicated amateurs
