Saturn storm+Tethys transit Aug 19th 2011

Hi All,

Imaged Saturn last night just after Sunset. The Jetstream had shifted marginally.


Saturn is becoming quite a challenge but as it is further South this year, the Palm tree that has thwarted my efforts over the last several years is not such a problem this year. Given good seeing I still hope to get more data.


I have 3 RGB & 807nm data sets at approx 20 min intervals. The best data set is the first one, the marginal seeing played havoc with the "B" channel as Saturn moved lower to the horizon.


My final capture was at an alt of 29 degrees.


There is also a transit of Tethys in this data. It is visible in the first RGB but not in the final two RGB's where the "B" channel deteriorated significantly. The transit of Tethys came up much better in my IR data.


Have attached both RGB & IR data sets along with their animations.

Thanks for looking.


Regards
Trevor
