Our sun is a typical star. We observe that a typical galaxy comprises on the order of 100 billion stars, which is equivalent to 0.1 trillion stars. Hence, this particular galaxy cluster comprises about 1800 galaxies.
From Wikipedia, we learn that:
"A galaxy cluster is a structure that consists of anywhere from hundreds to thousands of galaxies bound together by gravity."
Hence, a galaxy cluster comprising 1800 galaxies is not all that "mind blowing".
