This
            is my second attempt at this rather small object in the past
            decade. This image I feel has a better dynamic range and color
            correction than previous attempts. NGC7479 is 11.6th magnitude,
            and a diminutive 4 arcminutes in size. However this small but
            exciting object represents the SB(s)c class of barred spirals
            with blue arms and a sunny yellow core. You will note a few very
            small pink HII regions in the lower arm, and several bright blue
            knots along its length. The small edge on in the larger views
            to the lower left of the galaxy is MAC2305+1211, a 17.5 magnitude
            spiral that is only .5 x .1 minutes in size. The bright star
            just below NGC7479 here is 11th magnitude.
