Hi Eric,


Thanks for your latest Saturn. I can sympathise with you on how hard it is to image Saturn under poor transparency!. An excellent result for the high gain. The greenish colour of the SPC looks quite distinct, and also no spots at -40 are present at these longtiudes it seems.


Seeing has been terrible here in the early mornings, so nothing new from my end....


Best Wishes,

Hi Ed,


Excellent work. Thats the first amatuer image i have seen to capture those dark spots on Saturn, that are so well seen in the HST imagery. Tracking these could be rather mor difficult, since they are rather harder to record than the bright South Temperate spots. Hopefully someone will get some good seeing to capture this area again.


The spots on the Southern component of the SEB may prove very difficult to track, however the more prominent dark spot further south at around -40 lat may well be possible.


What a great apparition its turning out to be already!.


Best Wishes,
