Here are the Saturn images for May 21st 2015, taken in very good seeing
conditions despite some mist passing through at times.
These images have been the subject of intense speculation as we concentrate
upon the large storm in high Northern latitudes & the longitudinal
disturbances it appears to be generating in the associates regions...
Furthermore, there also appears to be a strong correlation between our
latest images & the most recent Cassini data that covers these particular
regions of Saturn...
In both the Cassini & our own images this large dark spot appears to be
surrounded by bright spots as well as smaller dark spots in adjacent
areas...
For us this is a powerful testimony to not only the excellent seeing
conditions but also the performance/characteristics of the ASI174MM
camera...
Here is an rgb image, plus an "inverted" rgb image which is very good for
identifying the bright (cyclonic) storms because they appear as strong dark
spots (ie, inverted) in this type of image...an r image plus an "r"
animation, r North Polar map & one with the r image heavily processed
compared to some of the latest Cassini images (May 25th) of these Northern
regions,
We have much more data from this & the next night which we will process over
the next week or so - any interested parties that utilise the ALPO-Japan
site & wish for further hi-res images (including ir610nm & ir742nm) from
these dates or other times can also contact us directly at
