Wei-Hao,
this is a stunning image! I did a similar mosaic one year ago
( http://canopus.physik.uni-potsdam.de/~axm/images/winter_hexagon.html ),
but yours goes a lot deeper. Isn't it nice when the zodiacal light counts
as 'light pollution'? <g>

This one also shows up in my image, although after quick look at the
Sharpless2 catalog
( http://xml.gsfc.nasa.gov/archive/catalogs/7/7020/index.html )
I think it is Sh2-245.
Just curious: did you notice any residual distortions after running
Registar? As far as I know, Registar only allows you to register two
images at a time. So, with three mutually overlapping images A, B and C,
you can register A/B and B/C, but this may not guarantee that B and C are
registered outside their common area with A.
Your anti-vignetting IDL program appears to be very efficient in creating
a uniform background - your mosaic shows not a hint of the seams.
Clear skies,
Axel
