Sun in Ha – 1 May 2015

Today there were finally some gaps between the clouds again. Tho, seeing conditions couldn’t be worse ( 1 / 10 ). So it was extremely challening getting any focus and capture enough usable frames.

SW Esprit 120 + Quark Chromosphere + TS 0.5 reducer + QHY5L-IIc . Stacked in Autostakkert and processed in Photoshop. The 3-frame filament mosaic is stitched in Microsoft ICE.

First, a 3-pane mosaic of the large filament structure. Eventho seeing was terrible, I am happy with the result:


Some other filaments:



A nice prominence:


And last, AR 2335, showing some flare activity:
