Sun on June 17th, 2012
Large sunspot group on June 17th, 2012. The 300 best of about 1000 frames were stacked and processed with Registax 6 and Adobe Photoshop CS5. Strong wind affected the seeing.
The images in the gallery were taken one after the other within only a few minutes respectively - the subtle changes in the detail are quite obvious.
