I have only 15s of continuous sunshine today after waiting for around one hour, cloud keep floating around, and to get surface detail in H-alpha, we need relatively cloudless... we can have some thin cloud moving, and to average them out by stacking, but then it's still unavailable today except this 15s. For prominences shot, I can push the exposure to pass through the thin cloud.

1336 (GMT+8), that 15s shot:-
1337 (GMT+8), exposure pushed to pass through the cloud:-
These two shots were taken with windows closed... so the glass is a killer of the quality, too... but for this kind of sky, don't worry.
