The following image of Jupiter and two of its moons was captured
by Adrian Brown at 22:08 UT on Sunday, 25th April 2004. It is a stacked composite of the best 200
frames out of 500 taken with an ATK-1C web cam through a Celestron CGE-11 f/10 Schmidt-Cassegrain
telescope. The moon Io is at upper left while Europa is near the right-hand edge of the frame. Io shows a
distinctly orange colour
in keeping with its surface geology of sulphur rich lava flows. The shadow of the moon Ganymede is
visible on Jupiter, although the Moon itself cannot be seen against the background of the planet in
this image. A wealth of structure and colour is evident in the cloud belts.
The following three images of Jupiter were captured by Adrian Brown
through his Celestron Nexstar 5 using an ATIK Instruments ATK-1C camera and a 2x Barlow lens on
17th March 2004 at around 20:40 UT. The camera is a modified Phillips Toucam designed to take
long exposure photography. A white oval is visible in one of the main cloud belts,
highlighted in the right hand image.
Four images of Jupiter processed by Graham Ensor from a stack of
150 AVI frames shot using a Phillips Toucam around 00:00 UT on 1st-2nd March 2004 through
Mike Dumelow's 8-inch Dall-Kirkham reflector. The images were additionally enhanced in Adobe
Photoshop. The Great Red spot is clearly visible, as are some smaller storms around it and
much structure in the cloud belts.
The following image of Jupiter is composed of a stacked set of video frames
shot by Graham Ensor
through the Society's 10-inch Newtonian reflector at the Flamsteed Observatory on the night of
16th-17th January 2004. Mike Dumelow provided a specially constructed eyepiece which fitted between the
telescope and Graham's Panasonic DV camcorder. The image was stacked by Graham using Registax software and
further processed in Photoshop to bring out detail. The cloud belts are clearly visible.
The above image is a normal contrast view of a section of the wider frame
shown below, in which the image brightness has been increased to show the moon Europa at left. Ganymede
can also just be seen emerging from behind the planet in the 8 o'clock position (it appears as a
bump on the limb of Jupiter).
