"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.

This is a very short CMY exposure, 18 min's combined color images and 45 min combined Ha.  Taken Friday evening from Whiting, NJ:  First attempt at CMY imaging.  6" Astro-Tech RC


Why CMY?
What's wrong with RGB?


I have both sets of filters, needed to try these, no special reason. I have a color filter wheel which contains the RGB and Ha filters. Will try them out next time. I looked on the internet and they were discussing the CMY and RGB differences, seems that the CMY filters provide more "detail" imaging??

Tried to call you, number changed.


Yeah I remember reading some but I stayed away from CMY cuz reminded me of the times dealing with CMYK for press - It wasn't too much fun

My number didn't change..sent u an email with it
