2. the pleiades 2. The Pleiades is an open star cluster located in the constellation of Taurus the bull. It is also known as the Seven Sisters, and also Messier 45. There are over 1,000 stars in this cluster which is characterised by a number of bright blue stars. The Pleiades is a naked eye object and will be seen as a fuzzy patch from which a few individual stars can be seen, my best view on a dark night revealed 4 stars, but others with me saw 6. Photographically the cluster displays blue nebulosity around the stars drifting off into space. With a low power telescope the beauty of the cluster is observed, with the stars shining like electric blue christmas lights. The Pleiades are easy to spot as they resemble a question mark “?”. 1. Saturn Saturn has to be at the top of everyones list purely for the WOW factor of actually seeing it with your own eyes. Saturn is the second largest planet in our Solar System, about 9 times the size of Earth, and is a gas giant. The striking feature of the planet is the system of rings that surround it. Although Saturn can be seen with the naked eye it is best viewed using a telescope. Even a small telescope you will be able to pick out the rings and with a larger telescope you will be able to see the divisions between the rings. Photo: Mike Barrett 1.
