	Magnitude: 9.3 Angular size: 7.4" X 6.3' 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. This image was taken with an 8-inch using a ZWO ASI 585 camera. Go to AP#48 M84 and 86 Return to AP100 main page.
