If you are thinking about getting into astronomy then a good start is to go and observe with someone else first. They will help you to get used to astronomical telescopes and learn how to navigate the night sky with one too. They will also help to show you what you will be able to see. You should be able to see the moon and all the planets (except Pluto), but some with more detail than others. On Jupiter, you should be able to see the bands and Red Spot, while you should also be able to see Saturn’s rings.
Many people recommend that beginners start off learning how to spot the planets and the constellations using a pair of binoculars first. This is indeed a good way to get started, and you may prefer to stick with your binoculars for a while longer even once you’ve got used to spotting the night’s sights. What’s more, if you find that astronomy isn’t for you, you won’t have invested a large amount of money in buying a telescope.
Astronomical telescopes are affected by weather conditions. The equipment needs to cool down to the outside temperature to give clear and focused images and this usually takes around 20 minutes, but could take longer depending on the temperature difference. Conditions are also affected by seeing conditions and this is down to both the weather and where you live. Large cities are heavily affected by light pollution which will decrease visibility due to excessive amounts of outdoor lighting.
