Hi,
I'm also searching for a good wide angle lens for astro photography (for my 60D). A friend of mine bought the Tokina 11-16mm. Over Christmas/New Year I'll see him again and I'll do some testing.
If u find good test results about the lens, pls share it
The Canon 10-22mm only have f3.5-4.5.
For a fix lens the Sigma 10mm f2.8 is quite good.
The Samyang (Walimex, ...) are not very good with f2.8/f3.5 ...
