This is a spectacular face-on spiral galaxy at the eastern end of the "T"-shaped asterism east of Denebola. I have seen some call it the "blow dryer galaxy". It is less than the 10' size limit but I placed it on the list because of the many galaxies that surround it as well as the galaxy's spiral structure.
