Sun in Ha – 21 April 2015

Today the skies were clear again, but seeing was worse than yesterday unfortunately ( 2 / 10 ).

Some fantastic activity on the limb today, With some nice loop prominences!

I did not had much time to image everything, so couldn’t capture all active areas like yesterday. Especially with the seeing being pretty bad, it was time consuming capturing decent enough frames.

I also took some flat frames today, to mitigate the uneven brightness in my surface images.

SW Esprit 120 + Quark Chromosphere + TS 0.5 reducer + QHY5L-IIc . Stacked in Autostakkert and processed in Photoshop.

First the nice loop prominences:
