I looked out the window tonight. Low in the Northeast sky was this brilliant scintillating star. I have seen them before, but never could really get a good video of it. I decided to take another approach. Video is not my forte. I setup my 7D for various high ISO settings and went for a pan shot across the star. I was trying to capture the colors of the scintillation in a band. I was amazed at how well I was able to grab the colors. These are not processed at all. I believe the star to be Capella.

That's clever use of your camera. Well done.

Most of that color is probably coming from distortion on the horizon or being below 20-degrees latitude . Capella actually is two golden stars but only seen in a high power scope setup to split them . They are beautiful to look at tho :

Yes, scintillation comes from a sort of "prism" effect due to the angle of the light passing into Earth's atmosphere. I suppose the brighter the star, the more pronounced the effect becomes. This one looked like a glittering LED light flashing all bright colors of the rainbow. Many would have reported a UFO. ;-)a

Just for fun, de-focus the star a bit.
The results are interesting.
