Dione in Transit ... just visible!


    

Upper:
It is just possible to make out the tiny dark shadow on Saturn's moon, Dione
projected onto the cloud tops in the northern hemisphere, immediately below
the dark green/grey belt, slightly left of centre. Its apparent angular diameter
was only 0.16". A white storm is in the southern hemisphere on a similar longitude
may just be seen as a low contrast feature. The rings are inclined at just 0.9 degrees.
Titan is seen to the right (west) of Saturn.
7.12.08   05:54 UT  Seeing: moderate  Transparency: quite good.
C14 @ F27; SKYnyx 2-0M CCD; Trutek R,G,B filters and Baader UV/IR rejection filter.


Lower:
The shadow of Dione is now approaching the right (west) limb. There now appears
to be two very low contrast white storms in the southern hemisphere. Titan is seen
to have moved since the previous image.
7.12.08   07:10 UT  Seeing: moderate  Transparency: quite good.

Occultation of Saturn by the Moon




The image was obtained a few minutes after Saturn had emerged from occultation by 39% phase thick crescent moon.

4.4.07

Saturn pre-2007

              22.1.06  

30cm Meade LX200 @ F25; Lu075M CCD



      3.4.05

Stack of more than 1,000 .avi video frames for each of the R,
G and B filters. ATK-1HS CCD attached via a x2.5 power mate
to my 30cm Meade LX200 SCT.




1.3.04

Stack of 120 images taken with SXV-H9 CCD and TeleVue 2.5x PowerMate
on my 30cm Meade LX200. The colour information came from images taken
through True Technology Ltd R, G and B filters.

Uranus


Uranus and its Moons

Quite a challenge! Here the brightness of Uranus relative to its moons has been substantially reduced
to avoid saturation of the image.


Left:

21.9.08   00:56 UT (central time for satellite images)
From top to bottom: Umbriel, Ariel, Uranus, Oberon, Titania.
Uranus apparent angular diameter = 3.66".
C14 @ F28: satellite data from SXV-H9 CCD stack of 192 x 2s; Trutek L filter and Baader UV/IR rejection filter binned 4x4
Uranus data from SKYnyx 2-0M CCD with Baader UV/IR rejection filter and Trutek R, G, B filters.


Right:

31.8.08   01:09 UT (central time for satellite images)
From top to bottom: Titania, Umbriel, Ariel, Uranus.
Uranus apparent angular diameter = 3.66". Seeing Pickering 7+ but poor transparency.
C14 @ F44: SXV-H9 CCD Baader UV/IR rejection filter,  Trutek R, G, B filters: R = 14 x 2s, G = 45 x 2s; B = 16 x 2s.


The green with a hint of blue colouration of Uranus
is due to the presence of methane in its atmosphere.
