Time to photograph some stars. If you live in a town or city with a lot of lights you might really struggle, because light pollution will wash out the stars, so you might need a trip into the countryside.
Follow the checklist; make sure you have got everything you need before you set off.
Once you have everything setup and working OK, experiment with shutter speed for different effects.
See if you can find the north star as a focus point, shoot one image with the camera towards, another with the camera away from the north - how are they different?
If getting out into the countryside is really too difficult, then find somewhere to shoot car lights at night instead.
