"Professor Goddard does not know the relation between action and reaction and the need to have something better than a vacuum against which to react. He seems to lack the basic knowledge ladled out daily in high schools."
--1921 New York Times editorial about Robert Goddard's revolutionary rocket work.

"Correction: It is now definitely established that a rocket can function in a vacuum. The 'Times' regrets the error."
NY Times, July 1969.

NGC281 Pacman

NGC281 Pacman

Monday night was another great, clear, windless night for imaging.  I spent 2 1/2 hours collecting 5 min images in Ha of the Pacman which is located in Cassiopeia, again while watching the S.F. Giants beat the Texas Rangers.  Tracking was right on.
