These few days, Hong Kong experienced a very hazy sky
due to air pollution.
The seeing was a bit improved to 4/10.

The sky was extremely foggy last night, cloud and haze leading to only two stars barely
visible on the sky : Jupiter and Sirius. My usual focal ratio (F34.5) could only captured
extremely faint Jupiter with low SN even I gain to mazimum level, so I switched to use F15
with 2.5X barlow. Although the sampling is under but still better than insufficient signal
to noise ration at higher focal ratio.

Surprisingly that this 150% resized do show some details and as the sky was extremely hazy
so the bluish festoons are much less obvious.

Kind Regards,
