Niels Haagh
Eyepieces and Barlow lenses

Niels Haagh from TrackTheStars will give a general introduction to eyepieces and talk the different types of eyepieces.

If the weather permits, the eyepieces will be tested in the telescopes outside. It is possible to borrow eyepieces for testing in your own telescope.
