"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.

Great for a first try!

Nice caputure on OIII - the outskirt halo, however it seems that when you combined the RGB, the Ha weight is too small.

You s'd do more NB imaging - is just spectacular what you can get
