NGC 4244 is loose edge on spiral galaxy in Canes Venatici. The size of the galaxy is 17 x 2,2 arcmin. She is in a distance of 14 Mio Lj and belongs to the M94 group of galaxies.
What is really interesting is the color shift from orange to blue from the center to the arms. Dust structures are visible in the core region together with plenty of star forming regions all over.
