Three solar observations

22/Oct: Went to a playground (football field!!!!) to observe the sun briefly with my friend, he has taken some afocal shots with his Coolpix 4500 with 18mm ortho afocally, I just had a look, no sunspots but some QRF and some nice prominence.

22/Oct: Did some b/w webcam solar imaging inside home when Alby was sleeping, found a tiny crack on the CCD protective window, I got to track it poorly in order to erase that crack after stacking. Need to find a long term solution for b/w solar imaging. The result was not bad, afterall. I even got an 1 hour sleep afterward. :-)

23/Oct: Did some afocal imaging inside home when Alby was sleeping, should not give any decent result, time to give up that camera since it gives too much compression.

I also processed some AVI from that camera, even with -EV, it still overexposed crazily and the images are compressed way too much, can use G channel for surface detail and R channel for prominence. File close.
