On Saturday night 8th August, I was able to capture some images of Jupiter with Io and its shadow in transit. The seeing was just above average – good enough to capture albedo features on Io, including the dark polar regions in contrast against the cloud tops of Jupiter. The best image from the session [...]

Jupiter, Ganymede + Shadow, and Wesley Impact Scar
Last night started like every other – typically below average seeing, but instead of going back to bed, I waited it out – hoping it would get better. And it did! The seeing peaked at 7 – 7.5/10, on a night when there was a fair bit going on. The GRS transited earlier, followed by [...]
Saturn with Rhea Shadow Transit
On Wednesday night I captured Saturn in above average seeing – the second time that week! When I’d finished processing the images, I noticed a faint Moon near the edge of Saturn, and a dark feature just under the ring plane. When blinking between the two images, I saw that the feature had moved, so [...]
Jupiter with Io and Shadow Transit Animation in Good Seeing
This morning, 7th May local time, I had reasonably good seeing for about an hour – long enough to capture 7 runs of Jupiter with the Galilean Moon Io and its shadow transiting across the Jovian disc. The red channel was pretty good in almost all images, but unfortunately the blue channel was pretty ordinary, [...]
My Best Jupiter This Year as the Seeing Finally Improves
Well it’s been a long time coming. Usually the seeing at my location is best between February and June, but this year it’s been horrible every day – I’ve been out trying to image Jupiter almost every clear morning for 2 months and have been increasingly discouraged at not having anything better than 5/10 seeing [...]
Jupiter with Io Shadow Transit, 29th March 2009
On Sunday morning, we had beautiful clear skies and I was able to capture an image of Jupiter with Io’s shadow in transit, followed by Io itself shortly after. Unfortunately the conditions weren’t great and the image is really affected by the poor seeing, even though Jupiter is now climbing to a respectable 40-45° in [...]
Incredible Saturn Transit Images by Hubble Space Telescope
On February 24 2009, a rare quadruple transit was taking place at Saturn. Titan, Mimas, Dione and Enceladus were all transiting Saturn, along with shadows of 3 out of the 4 Moons! Fortunately for us, the Hubble Space Telescope was on-hand to image this extraordinary event and these beautiful and fascinating images have just been [...]
Titan Transit Images – Wrap Up for 2009
The last transit of Titan across Saturn for 2009 occurred last week, on the 12th March. Unfortunately, yet again, I was clouded out for the event so I have had to live and love it through the images of others. Some friends of mine from IceInSpace and other forums were able to capture some great [...]
Titan Shadow Transits on Saturn in 2009
There’s already been three transits of Titan across Saturn in 2009, and maybe, like me, you’ve been clouded out for most of them. All is not lost, however. There’s still one more transit of Titan itself in 2009 (a grazing transit, with its shadow, on March 12 at 22:15 AEDST (11:15 UT)), followed by a [...]
