Observe Jupiter’s anticyclone

The gas planet’s Great Red Spot never fails to disappoint

You’ll need: A telescope A selection of eyepieces ✔ ✔ Coloured filters A notebook or drawing pad ✔ ✔

1Use a tracking motor

Set up your telescope with a tracking motor if you have one. It’s essential your instrument has been assembled on a level surface to avoid wobbling.

2 Use a low-power eyepiece

Eyepieces that combine with your telescope for a low power should be used first. Switch to a higher magnification if the observing conditions are fair.

3 Attach a coloured filter

Experiment by using various coloured filters. Start with a light yellow filter to enhance the contrast of Jupiter’s atmosphere.

4 Use an ephemeris

It’s good to know when certain features will be on view, so use information on the internet to find out the best viewing times.

5 Find the Great Red Spot

This particular storm is not always visible, but when it is, take some time to make a note of its colour and shape. It’s spectacular to view.

6 Take notes or sketch Jupiter

It’s great to keep a record of what you see. Draw a circle on some paper and fill it in using coloured pencils to record Jupiter exactly as you see it.
