Re: [APML] Film/CCD collaboration: new images

Hi Jeff (and Mike):
Very impressive collaborative images! Jeff, I also very much liked the SEDs
URL that you provided with the Horsehead
(http://www.seds.org/billa/twn/b33x.html). Can you decribe how you navigated
to this Arnett site? When I go through SEDs, I get all sorts of individual
images of B33, but I never seem to end up at this nice map and panel of
thumbnails.
Thanks,
Bert
