>As one who enjoys observing comets I am almost invariably dissapointed by
the comet photographs displayed  in public forums (fora?). Almost without
exception the coma of the comet is completely burnt out in an effort to show
as much tail as possible. Yet is in the inner coma where most of the
activity takes place and where much of the interesting structure is to be
found. The problem is the limited brightness range of both CCD and film
which makes it difficult to record the widely varying brightness range
betwen the nucleus and the outer coma.

would challenge any astrophotographer to come up with amount of detail I
could see in the Comet Hartley 2 inner coma.
