"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.

M51 on a clear night

M51 on a clear night

Another night of perfect skies, just before the muggy weather comes in this weekend.  Tuesday evening I took M51 combined one hour exposure.  Orion 80ed on Vixen mount.  There is another galaxy lower left hand corner, 14 mag I.C.4263, highlighted in dim circle.

Miss the clear night

Nice!

I was way too tired but did notice a nice clear night

Glad you took advantage of IT

Tonight seems even better but I'll miss it again.

I hope you can add more time to m51 ;)

Send me the raw fits combined file
