Nice Website.
Should use your full name instead of just Trevor if you want people to use your images but acknowledge the source.
Also the sentence "
I like so many others with the advent of the digital SLR's, cheaper CCD camera's and the relative cost reduction in obtaining equipment capable of producing good results, excellent images are now being produced by a proliferation of astro photographers worldwide, images that were near on impossible even to the professional some 10 to 20 years ago." is too long.
Cool site though and I really like he first image opens up !
well done
good work 
cheers
