Saturn 5th May

Hi All,

Imaged Saturn last night over a 95 minute period.
My aim was to image the second longest lived storm recorded on Saturn.
The storm is in the STrZ and was to be in the region of the Central Meridian at 13:00 UTC.

Was setup early and captured four RGB's from 11:20 UTC to 12:55 UTC.
I have posted the four RGB images plus an animation of those images.

Image 1
Was captured in very good seeing 7 to 8 /10
There is a cloud structure highlighted in the SEBZ

Image 2
Still very good seeing 7 to 8 / 10
The structure in the SEBZ is still visible and the storm I set out to image is entering stage right in the STrZ.

Image 3
Murphy has a lot to answer for, high level cirrus started wafting through which reduced my signal, although the image still looked good but dimmer due to the filtering affect of the cloud.

Image 4
With a much thicker region of cloud about to encroach on Saturn, this was my last RGB. With less signal this is the grainiest of the four but the storm in the STrZ is visible.


The animation of the above four images highlights the movement of the storm in the STrZ. The feature in the SEBZ is harder to pick as it is only in the first two frames before it is lost in the East and the first two frames were 40 minutes apart.

With the quality of data I am getting now it is time to start looking for more magnification. I think I might start saving up for a 4x Powermate.

Thanks for looking
Regards
Trevor
