Saturn storm in STrZ 3rd June 2009

Hi all,

Imaged the storm in the STrZ tonight, captured 4 sets of R, G and B avi's each avi was 900 frames. Stacked the best 350 from each avi.

To capture this feature I had to be imaging at 6:50 pm CST, this was relatively close to sunset and the ambient temp drops very quickly early in the night. I struggled to maintain my primary mirror within the .5 of a degree C tolerance that my optical system seems to require for optimum performance, depending on the seeing.

Tonight the rings were open just under 4 degrees, relative to the Earth.

The seeing was quite reasonable at about 6/10 and improved through the night. I have attached the best RGB image and an animation of the four. The animation represents the movement of the storm over a 50 minute period.

Thanks for looking
Regards
Trevor
