"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.

Bubble

Was extremely clear Friday evening and a decision to take images rather than going north to Livingston which would have been an hour and a half up, three hours there, hour and half back home .   The image Bubble Nebula (NGC7635) is located in Cassiopeia, sometimes classified as a planetary nebula, actually closer to a ancient nova remnant.

This is an updated image just taken on  Oct. 29, only it is a combined 23 x 5min images, processed in Photoshop.  Compared to the previously posted 2 hour image which was 3 min images.     Tracking was terrific, clear skies, no dew, no wind, 53 degrees at 11:30 PM.   Watch Comedy Central while keeping an eye on the computer and telescope (on the extended patio rear of our Sun room).  THIS IS AN EXPERIMENT IN PHOTOSHOP CS4 adding color and making it possible to see "thru" the Bubble.  Hmmmm
