Description: I spent over an hour with M87 and was able to see something in the right place several times. The jet wasn't sharp because of seeing (?) but there was clearly somekind of overhang pointing to NW from the core. It was visible only occasionally. 5 mm Baader Hyperion gave the best views @ 457x. The jet is very close the core. Two small galaxies on the SW side were much easier than the jet.
