Light pollution panorama

Richard Muhlack kind of prompted me to make an image of the severe light pollution of my area, so tonight, I made a near-360° panorama of 2.5" exposures at f/1.4 / ISO 400.

This was taken with a near full moon, well after end of daylight. Obvious are the incandescent street lamp and the mercury vapour ones (not to mention the 3 oher Hg vapour ones behind the houses).

Tripod was placed EXACTLY on the spot I set up my astro-imaging scope rig.

With a DSLR, I was fighting HORRENDOUSLY to get any useable images out of a session, but with the CCD and the software light pollution reducing filter S-X uses, I can extract a LOT of data from VERY few exposures. I MAY try LPF's again on the CCD to see any improvement.
