Technical notes

This guy did a few tests and said "All was shot on a Canon 20D SLR (ISO 400, F-Stop 5.6 and 25 second exposures)."

I have read that ISO 400 the common ISO for night sky photography to avoid any grain in the pictures. Anything lower than 400 would be even better, this will have to be something for me to test out.

He also mentions his editing together of the photos for a smoother look " I just took approximately 300 photos
and brought them into Final Cut Pro at 2 frames each."

In terms of the exposure, I think I will use a variety of different exposures. In this next video, the guy does a star timelapse with a long exposure which makes the stars look as if they are falling bombs from the sky. A great idea (though possibly ruined by his choice of "colour changing" edit) which gives a great effect.
