By chance I came across a some what odd behavior of Guide8.

When I thought I should have a glance on NGC 7840
(RA 00:07:09 / DEC +08:23:01, the last object listed in the
New General Catalogue) Guide8 pointed me to the exact
zero point of the sky (RA 00:00:00, DEC 00:00:00)
some degrees apart from the right position.

The Legend reported Millennium page 1279 going W
and Millennium page 1818 going E from this point.

When I directed Guide8 via Go-to-Coordinates to the right position
then the Legend reported Millennium page 247 going W
and Millennium page 270 going E from Vernal Equinox.

The real odd thing is, the last (highest) page of the Millennium Star Atlas
is 1548 (perhaps a hard nut to crack for Bill?).
