Webpage screenshot in Ubuntu: large webpages

[Dotan Cohen]

I just discovered this terrific solar system scale:
http://www.phrenopolis.com/perspective/solarsystem/

I would like to export it as a .png image, but I cannot figure out how
to do that. I have been playing with wget and imagemagick but I just
can't do it. Googling finds Firefox addons that do not support such a
large page and Windows software. Any ideas? Thanks!
