Issue with cutting out circles

[Cillahughes]

Ok, So I'm new at graphic Design, but I have been using Photoshop for a while and have CS6 (just in case it makes a difference in my responses)

My problem - I have been designing some cover work for a while now for 1 person for his music,

The idea is to get an image, cut a circle from it, then a smaller one inside that (- rotate this one at the end of the process) and then another smaller circle inside that

My problem arises when I go to cut the second circle, I am using a fixed size and working in pixels, so For the first circle the size is something like 1342 px X 1342 px

Then my next one is 1032 px X 1032 px

Next is 724 px X 724 px

Now, when I got to rotate the middle circle I end up with it not rotating perfectly, I have the center spot in the same place but I have a band appearing around the edge, it's like it isn't a perfect circle, though i'm sure it is because of how I have used the measurements...

Please, where could I be going wrong?

Do you have an example of this, a screenshot perhaps? My first thought is that it's a result of working with pixels, the smaller the size of the circles, the less smooth the outer edges will be.

Yeah i'd say Paul is right. Do you have illustrator?
