Was gone for most of the day, but managed to get an image in before sunset.  I also gave it a first try to image the solar prominances in Ca-K.  The  flares were captured with very high gamma and long exposure times.  I am not sure if these flares are not bleeding in from the Ha or other lines.  I will have to test that with an Ha scope sometime.  You also can see the rotation of the sun comparing these images to the one from yesterday. :-)
