20071117 Sun (prominence and AR974)

Seeing was 2-5/10, transparency 6/10, two big prominence, one small active region. Borg 45ED II, SM40/BF10 used for low power shots, C5/PST used for high power shots.

Surface detail at 1247 (GMT+8) and prominence at 1249 (GMT+8):-

Close up of AR974, detail shown in the photo below:-

Prominence close up at 1316 (GMT+8):-

Prominence close up at 1318 (GMT+8), this one is dimmer than the above one:-

Finally, a poor attempt to capture closer up (2x as above, i.e. ~2500mm) of 974, seeing obviously couldn't support:-
