"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

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.

M51 on a clear night

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
