Saturn 1999.

20 Aug 1999 : Saturn, same telescope and method as for the Jupiter images. To the left, an average of 12 images at 0.5 s integration time each. To the right, from the same set of images, an average of the two best images.

1 Sep 1999 : as for the Jupiter image of 1 sep, I was imaging in undersampled conditions with 18 micron binned pixels but this image does not seem to suffer as much from this as the Jupiter image does.

250 mm f/15 SCT + TV 1.8 x barlow + red filter and 0.11 s exposure.

12 oktober 1999. I used my 250 mm f/15 SCT + 1.8 x Televue Barlow + red filter. ST-7 working in 9 micron resolution at -10° C, exposure time 0.2 s.

4 images were averaged and an unsharp mask was applied in AstroArt.
