≪石川県小松市 大杉忠夫≫[Tadao Ohsugi:Komatsu city Ishikawa pre,Japan]

A real pity that I had less than ideal atmospheric conditions for Saturn's opposition yesterday.
However,the interesting Seeliger effect was well seen. The planet shows as a bit dim,
but I have deliberately retained the true brightness contrast,whilst trying to ensure that the brightest regions were not "burned out".
To the best of my knowledge,this is 5-6hrs after true opposition.






I also took the opportunity to capture some CH4 data.
However,in this instance I have adjusted the gamma slightly to brighten the planet's disk.
Unless proven otherwise,I am assuming the bright features on the inside of the rings are artefacts.
