   * Exposition should not change. Lock exposition or keep the shutter button half pressed when you shot.
   * Ideally, use a tripod perfectly horizontal
+  * As far as possible, the camera should only do a rotation, without translation
+  * It can be interesting to use the camera in portrait mode, to increase the vertical field of view of the panorama
+  * It is also possible to do multiple rows for even larger vertical field of view
 ===== HDR (High Dynamic Range) =====

+==== Tips ====
+  * Force a low ISO
+  * If the photo is dark like stars, you should take a //dark frame// to subtract the pixel noise. With Gimp: open the image, open the dark frame "as layers", in the Layer dialog change the mode to "difference", flatten the image and save.
