20080517 Sun

It's essentially cloudy, transparency is like 1/10, the sky is all white, and we have a very dim deep orange color sunshine. Seeing is like 4/10, actually, quite hard to evaluate. There's not much prominences detectable. Several small active regions (AR994, 995 and 996) can be seen despite the very poor transparency which washed out most detail.

Telescope: Borg 45ED II
Filter: Solarmax 40/BF10
Camera: DMK 31AF03

1352 (GMT+8), surface detail with prominences pushed:-

1353 (GMT+8), prominences centric exposure:-

1355 (GMT+8), again surface detail centric exposure, alternative color scheme:-
