Does anybody know what value I should be using for the Absolute Position on Jupiter to get the red spot in the correct place in the Jupiter 2 program?
The link sends you to a web page that indicates it should be around 140, but that doesn't tie in with Carts du Ciel's view of Jupiter. I haven't been able to check it visually as every time been out the spot has been on the other side.
Thanks

Hi KimB,
I think you should use 138 for the GRS. Yep just checked Sky and Telescope here. Check the next to the last paragraph in this article.
peace & clear skies,

Thanks for that Carl, looks like my Cartes du Ciel was wrong. I found an option to correct it under Preferences, Catalog and object parameters... , Planets tab.
Now if the weather clears and my telescope works, I might just get to see it tonight just before it disappears round the planet.

Yup.
138 degrees as Kolchak the Night Stalker said.
