Clear Skies on the 8th. Spend a lot of time a little below freezing to image the Sun in H-Alpha as well as visible light with green filter. The skies were stable enough to let me image at 1600mm but the C11 had to stay inside. Here a nice comparison of the same area on the Sun with Active Region 1944 using the SolarMax40 and the Stellarvue SVC80 with some nice details even extending in the umbra. The size of AR 1944 is huge at 1560 millionth and one can easily make out the two largest spots with the naked eye using eclipse glasses..
