Also, thank you Neufer for reminding me of Lissajou orbits, it's only been 2 years since I'd thought about them last but had already almost completely forgotten about them, haha. It's a shame I don't use more of the stuff I learned in college, but such is life. Pretty much any orbit utilizing the Lagrange points is pretty darned fascinating though, it's a shame they aren't used more often, YAY for JWST!! Can't wait for launch.

Hi,
That's part of the whole picture that I simply don't understand, why did those points of light (stars) also scintillate?
I used photoshop many moons ago ver. 3.something. I do not profess to know much about its power, But I asked the question, if light is distorted by the atmosphere, then should not all light do so with varying wavelengths being distorted/scintillated in different ways?
The other, and I believe is the most important point, the shutter was open for 10 seconds. I'm no mathematician, nor a qualified Astronomer, but I passed with As and A+s in all my Maths and physics.
Many many moon ago, I am an authority on Telecommunications (35 years). But from my slowly fading memory, I asked the question. Look at any 10 second exposure, how many points elongated do you see? then if the camera is swung why are there only 2 points.
I am only asking, and I believe very good questions.
If I look up at night with a camera I cannot Isolate any single point of light let alone 2 in the same frame.
That is my only question.
I don't get it.
I thank all the replies, I know the 'CRO' Lysaght display well, period/time(?).
But the question is to the whole and not to the 2 points alone. Would a camera and 10 seconds of an open shutter produce 2 points of scintillating light.
I ask with the scientific principle, if it can be reproduced by anyone (all) then HUMBLE PIE I WILL GLADLY EAT.
Thank you.
No Offence indented.
Kindest regards.
