For use with or without a telescope?
Bright Star Atlas ($29.00) has stars to magnitude 6.5
Sky Atlas 2000.0 (Deluxe) 2nd Ed. ($79.00) has stars to magnitude 8.5
Uranometria All Sky Edition ($99.00) has stars to magnitude 9.75
Note all have deep sky objects but there are more in the versions that show more stars.
I would highly recommend the Sky Atlas 2000.0 (Deluxe) 2nd Ed. as it is a large scale atlas (A3 and is in colour). My first atlas and one I still use is the first edition of Sky Atlas 2000.0 (Deluxe) which I bought off the shelf at Dymocks a long time ago. The colour version makes it so much easier to identify objects during the night and also for armchair study during the day.
The second edition (Deluxe) has star names added and an extra 0.5 magnitude of stars over the first edition.
The Uranometria atlas is good if you own a large telescope (10" and over) or intend on getting one. Don't be surprised if you end up with one two or all three of the above as all have uses. I started with Sky Atlas 2000 so I don't have the Bright Star Atlas but do have Uranometria (previous edition). I still use Sky Atlas and Uranometria depending on what I'm looking for.
I think you will soon out grow the Bright Star Atlas as it only has stars visible to the unaided eye and if you use it at the telescope there will be a lot of stars not shown in the atlas. Of course as telescope size increases this is also the case with the other two but the main purpose of the atlas is to get you as close as possible to an interesting object through a series of star patterns on the chart that match the real sky through a finder or low power telescope view. For this you want lots of stars on the atlas and a nice large scale.
Note not all objects that are in any atlas are going to be visible and there are companions to both Sky Atlas and Uranometria that show lots of details about each object on the charts and you can determine whether a particular object is going to be visible in your telescope.
