7.76 KB Finally a good image showing the Great Red Spot! It has been hiding on the back side in all previous attempts, and last year it was quite pale. Here it is seen in nice colour. Image shot at 22:34 UT 19. Feb 2003. C8 + 3x barlow + ToUcam 740.

45.62 KB After a long period (1 year!) of bad seeing, a new opportunity came. This image was shot 18. Feb. 2003, 20:49 UT, and it shows the silhouette of Io in front of Jupiter. Io's shadow is seen in transit across the surface, and Europ is seen at lower left. Lots of cloud details!! C8 + 3x barlow + ToUcam 740.

Reprocessed version, Greatly improved of the January 6. Jupiter rotation video (see below). This version is an animated GIF, 58% size, slow motion, eternal replay.

5.02 KB February 19, 2002. C8, 3x barlow, Philips Vesta 675 webcam. Conditions were generally much better than what we have seen in a long time. Clear skies, no wind, dry. Processing was done with IRIS using compute_trichro1 command.

8.65 KB February 10, 2002. C8, 3x barlow, Philips Vesta 675 webcam. Temp +2C. The first night in weeks with imaging options, but the clouds destroyed the session after about 25 minutes, and the conditions were generally poor. The image shows Europa in shadow transit. Processing was done with IRIS using compute_trichro1 command.

225.05 KB January 27, 2002. C8, 3x barlow, Philips Vesta 675 webcam. The sky was nearly opaque due to increasing cloud cover, -12C. GRS is visible at upper left.

Removed, see above January 06, 2002. C8, 3x barlow, Philips Vesta 675 webcam. This is an MPEG video (383.13 KB) showing the rotation of Jupiter from 20:43 UT to 22:17 UT. The sky was steady but very far from transparent, -5C. Can be presented in Windows Media Player, but if you want to reduce the speed, I recommend IrfanView

15.91 KB December 16, 2001. C8, 3x barlow, Philips Vesta 675 webcam. Conditions and techniques very similar to December 12 image, but this time Jupiter was close to zenith.

13.75 KB December 12, 2001. C8, 3x barlow, Philips Vesta 675 webcam. This image has been stacked from 22 frames selected from a 123 frame AVI. Van Cittert deconvolution has been applied, followed by contrast streching and colour channel alignment. I am pleased to see the details are becoming clearer, even though the seeing was not perfect. Temp -7C. GRS at upper left. Click here to see a 631KB MPEG version of the original video (replayed at 4x speed).

6.99 KB December 10, 2001. C8, 3x barlow, Philips Vesta 675 webcam. Another step forward in quality! This time Ganymede has been caught in shadow transit, and the Great Red Spot (GRS) is visible too.

jupiter_20011119.jpg
8.10 KB November 19, 2001. C8, 3x barlow, Philips Vesta 675 webcam. A great improvement, even if the planet was a little low in the sky. Reasonable seeing, -4C. You can see the scope has been properly collimated!

jupiter_moons_20011005.jpg
7.74 KB October 05, 2001. C8, prime focus, Philips Vesta 675 webcam. The image of the planet was shot with a 3x TeleVue barlow (under horrible conditions) and superimposed on the prime focus shot of the planet and moons.
