20180520 Sun

Summer came, and the direction of the sun inside my room is no good.

Seeing 3/10, transparency 7/10 - nearly the best we can get here in Hong Kong.

0642 (UT), exposure optimized for surface detail, prominence was pushed by post-processing.

0644 (UT), exposure pushed up to show the prominence.

Relatively lack of surface detail, some nice prominence around the edge.

By poor viewing angle, there is only around half of the aperture was illuminated.
