20070531 Solar Mosaic

Seeing is like 3-4/10, transparency seems high at 7-8/10, but it's very low contrast due to thin and scattered cloud, it is a killer of any good H-alpha solar imaging. Nearly zero detail can be detected visually, very bad indeed... I even suspect decontacted etalon!

Nearly zero prominence could be seen, which is very rare indeed, solar disc surface activity is low too, we could only see a few short filaments around.

Failed again, each of the below consists of two raw frames, click for full size:-

Finally, made them together despite they didn't really match:-
