Notes

This fine edge-on Sc spiral galaxy is just one of many island universes in the local Canes I Group. Containing about 40 members brighter than apparent magnitude 15 and showcased by the bright face-on spiral M94, the Canes I Group is a close neighbor. NGC 4244, estimated to lie about 6.5 million light years away and span a diameter of approximately 65,000 light years across, is receding from earth at a respectable 493 km/sec. Numerous HII areas can be seen in the long tracings of the spiral arms as well as a delicate sampling of dust lanes surrounding the nucleus.
