Solar observations at Tyyrinmäki Observatory. The weather was clear but the wind was incredibly cold.

The first two images in white light: Astrosolar film, 9.25 '' Celestron SCT.

Images: Lunt LS50 THa, with simple filter.

Current main observation system. Power sharing and USB on the same hub (Pegasus Astro Advanced Pocket Powerbox). Quite an incomparable device.
