Sun in H-alpha 20070529

Finally, the sky cleared and yesterday (2007-05-29), Leo, Michel and me went to the hill to test the new solar telescope of Leo. Thus, around 17:45 GMT we captured some images with a small digital camera (Werlisa SLIM 30 Pro) attached to the telescope. After some processing, the following image was produced:

The image processing was as follow:
  • The original caption was transformed into a grayscale image.
  • The grayscale image was transformed into a RGB image.
  • A color map was applied to each channel of the RGB image to show in the same image the prominences and the surface details simulating as possible the observed colour.
