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.
