Saturn 1997-2004
SATURN through the years:
Different images made in the 1997-2004 period
latest: Jupiter 24 nov 2000
Short movie of Jupiter and Io 24 November 2000
JUPITER and IO 24 November 2000.
Three images from the Jupiter Movie, taken with the FT1020 CCD-camera. Each image is a sum of four exposures of 0.5 seconds and processed with an unscharp mask (Orginal*HF-image).
Date: 2 November 1999 around ~22:00 UT
Scope: 25cm Newton at f/D=44
CCD: FT800 with colour wheel
Exposure: R 6x0.4sec, G 6x0.2sec, B 6x1.2sec
Remarks: Each colour unsharp masked
IMAGES taken on january the 23th with the FT1020 colour CCD in Frame Transfer mode (512x512pixels). Especially in case of the relatively fast rotation of Jupiter, the simultaneous acquisition of the RGB-images is an advantage compared to using the filter wheel with the monochrome FT800 CCD (top image). In the latter case the rotation of Jupiter during the time needed for acquiring the successive R,G and B images is usually enough to cause a slight misfit when combining the R,G and B images to a colour image.

Scope: 25cm Newton at f/D=60
Exposure: Each image 1.5sec or sum of 2x1.5sec
Processing: All images unsharp masked
Remarks: Size of Jupiter 39.5" (10" smaller then during opposition)
Note the rotation of Jupiter and the red spot, just slipping around the corner in the first images

Date: 21 September 1998, 23:40 MEZT
Scope: 25cm Newton, Barlow projection at f/D=13.4
CCD: FT800 with colour filter wheel
Exposure: Red and Green 0.1sec; Blue 1sec
Remarks: Moons of Jupiter from a second, longer exposed image
CONJUNCTION of Jupiter and Venus, 23 February 1999 18:00 UT.
FT800 in prime focus of 25cm Newton (f/D=5.7) with BG12-filter to enhance contrast on Jupiter and avoid over-exposure of Venus. Jupiter unsharp masked; Jupiter, moons and Venus are shown with different brightness settings
Exposure time: 0.2sec; Field of view: 11' x 15'
Object: Mars around opposition (diameter 16.2")
Date: 3 may, 26 may, 28 may and 1 june 1999
Scope: 25cm Newton at f/D=44
CCD: FT800 with colour wheel
Exposure: R 4x0.4sec, G 2x0.3sec, B 3x2sec
Remarks: Sharpened with HF-structure of R-image
Jupiter and Saturn above the Dolomites (Italy)
Date: end of july 2000
Standard camera with f=50mm objective at f/D=3.5
Exposure: 15 seconds
