Dear friends,
Seeing and transparency are similar as 2nd June in this morning. I was able to capture some shots. This one was captured at 21:24UT. This time I increased the Focal Ratio to F42 (approx). As the transparency is not pleasing, the image appear a bit noisy (80% gain) after processed. Seems high focal ratio is better be used under high transparency. No visible dust acitivities detected.
The AM limb brightening is well shown on the image. Also the NPC hood is smaller. The SPC is very bright and some region is saturated.

It will be rainy days until early next week in Hong Kong according to the weather forecast, I can take a rest already. :-) Hope I can get well prepared to meet Syrtis Major region.
Cheers,
Eric Ng
