Thanks for showing me my problem. What you are saying is that the rippling is not due to seeing but to local currents. And now I am forced to agree. There is no active cooling in the C14 tube but I let it equillibrate for hours.. (our tube needs to warmed, not cooled!) but I am shooting from a concrete pad over my roof about 2 hrs after a 90 degree day. I'm only about 30 ft from the roof and Jupiter is about 25 degrees above the roof. Not much I can do other than blow up my house. You know what? I'm thinking of hosing down the roof before I observe. Desperate people do desperate things. When I get home I will be anxious check out your .avi file. I just compress mine for upload as you cannot upload the uncompressed movie. In fact this was a quicktime movie converted to an .avi and uploaded to YouTube. I'm bringing the C14 to the dark Florida Keys next month in an effort to address the problem. This year Jupiter gets no higher than 49 degrees in Miami. Not so in Australia obviously, as I saw that Jupiter can get as high as 80 degrees this year for Australians. It will be several more years before Jupiter can get that high for us. It also doesn't help that in Miami in the summer you get only 2-3 nights a month where the sky is clear enough around midnight for planetary photography. But I will keep trying. It could be worse. I could be living in New York State where I was born and Jupiter never gets above 28 degrees this year.
