* Reasons why they can’t be seen... Too feint, too small, too much light pollution, not a big enough scope, eyes not sensitive enough, need to use a camera and a long exposure. (Heinrich Olbers is visible in the bottom of the screen for this question, he comes up in session 4 – however his paradox can be mentioned now if you like – this is the first of many cross over points between the sessions.) | * Reasons why they can’t be seen...

* Star trails picture taken over around a 2hr exposure (from the size of the trails – full circle = 24hrs) Foreground image and star trails are NOT taken at the same time with same exposure – this has been edited. Note the “pole star” doesn’t appear to move (much) | * Star trails picture taken over around a 2hr exposure (from the size of the trails – full circle = 24hrs) Foreground image and star trails are NOT taken at the same time with same exposure – this has been edited.

Find Polaris using the pointers. Hit the big W of Cassiopeia and you have gone too far. Note the “pole star” is not actually that bright, and due to precession of the Earth’s Axis it will not always be on the pole. | |||
