Visibility IV / V

Ben Kalland, Ursa (Helsinki)

I photographed the morning sun in the hydrogen alpha. The sunspot group AR 12835 and the prominences were handsome. This is my first h-alpha My picture, if not the very first completely incorrectly focused attempts are counted now. It takes a bit to study more image processing, but I’m pretty happy with that too.

On todella hieno. Ja tuolla Luntilla voi hyvää jälkeä odottaakin.
