Sunspot AR2781. Good seeing for this session, allowing for both white light and H-alpha images with the 150 mm refractor.

A short 13 frame animation showing the activity inside sunspot group AR2781. Note the in/out of the plasma along the magnetic lines all around the main sunspot at right. Also the many Ellerman bombs emerging around the main spot.

150mm achromat, ASI174MM, Quark H alpha filter. It was also the first test of the 228 mm H-alpha refractor. Despite the degrading seeing conditions and the low altitude of the Sun, the image of the main spot of AR2781 shows some interesting details like the plasma “flower petals” lines, surrounding the core.
