Paul, I remember, and rather vaguely at that just now, Tom Polakis took some
images of The Hubble Variable Nebula over an extended period - perhaps a
year or so. Put together a nice gif/jpeg to show it changes. It was quite
a hit on the internet.
Tom is my memory correct an if so are the images still available?

Paul Lind and I aimed telescopes at the universe at Hovatter Norte =
Tuesday night under amazingly clear and transparent skies. Comet Holmes =
is, indeed, quite spectacular to the naked eye under such conditions. =
Through the 25", it is a huge splash still with a razor sharp edge on =
one side and lots of stars shining through. It has become much more =
elongated. The finder view was great, but the naked eye view is the most =
startling. =20
The bigger news is that the Hubble Variable Nebula (NGC 2261) appears to =
have changed dramatically since last season. It is no longer connected =
to R Mon; there is big black void between it and the outer, fan-shaped =
glow we are so familiar with. Lots of intricate structure in the =
transition in the 25". Or, am I just remembering this wrong? Sure =
seems to me that the last time I looked, that the big void between fan =
and R Mon wasn't there (or at least was just a stringer in the fan).=20
Take a look and see what you think.
Also, can anyone compute where the gegenshein was last night (Dec 4)? =
Lind and I were struck by an unusually distinctive bright glow just off =
the open end of the Taurus "V", right where NGC 1647 is (only much =
bigger than 1647). The sky was so great we were wondering if this is =
outlying Milky Way. It was certainly near where we thought the =
gegenshein should have been.
