Sunspots. Pictures taken with a ten cm. refractor, ( Bresser), F1000, 25 mm, 15 mm and 10 mm eyepieces. And a Sony Alpha 5000 camera, handheld against the eyepiece. Afterwards the pictures were split in three colours in a paint program on my PC, the blue one of the three parts, was thrown away, and the picture was put together again, and i had a look atnthe dark/light, and contrasts.
