yeh I've seen his work before, absolutely awesome stuff.
I mean he's got many many thousand dollars worth of equipment there.. goes to show that good equipment is essential for good astrophotography.. but i'm sure that's only 1/4 of the effort.. most of the work would be in the technique of capture and the post-processing of the images afterwards..
While i'd love to be able to capture images like that, there's a couple of things holding me back

1. equipment
2. money, to buy #1
3. time - to do those sort of images requires hours and hours of exposures over many nights.. i just can't afford that time at this stage of my life with 3 young kids and commuting for work.
Maybe one day
Still, very nice to look at and it definitely gives you something to strive for.
