I am using a fits image to look at ngc1097. The radius of the galaxy is roughly 600 pixles. I want to cut this part out into a new array so I can work with just the galaxy. Does anybody no how to do this.

I was thinking of selecting each area above to the sides and below the galaxy into a new array then subtracting this from my original array.
