And also Matty, the program Star Trail.de is this one a free download, or can it be purchased somewhere.

Hi Leon,
You are correct. A 20 minute sub will have the exact same result as 40 x 30 second subs.
I was going to use 10 minute subs but decided against it. 30 second subs work just fine.
You can download it here for free.
