Planetarium SoftwareSome 10 years ago I purchased a copy of Redshift 2, this was a stunning piece of software at the time, although I felt it was not exactly intuitive to use.
2 PCs later and I thought I'd see what was on the web in the way of downloads, well the first I discovered was Cartes du Ciel. This is a very thorough piece of software and will let you print charts based on your date/time/location so that you can take up to the minute charts outside with you. A link for this is in the links section.
Last night I noticed a post on the SPA forum which mentioned a package called Stellarium, so off I popped and got a free copy. As far as looks and ease of use this package will blow you away. It looks simply stunning, I hear that Starry Night is better, but this is freeware! But, you cannot print charts!
So, I'd recommend Cartes du Ciel if you want to print charts but if you want what amounts to a simulator of the night sky then Stellarium is the best. Why not use both, I will!
