For astronomer; helps polar align your equatorial mount.
Mise en station is a little free utility for amateur astronomers. It helps you to polar align your equatorial mount using the drift alignment method. In fact, \"Mise en station\" basically acts as a reticle with motion tracking capabilities.
I wrote this software for my own needs (I do not see the pole star from my balcony! ) and I wanted to use my Philips SPC900NC webcam on my laptop Mac. Many other webcams might work but this has not been tested. Try and see!
