photo help-green haze?

Hello all, I took these two photo's Friday night. The sky was quite cloudy so I only got about 20 frames duration between 45sec-1minute. I used Astrophotographers Tool software to control the camera and PHD to guide with autodither on for the first time.
I processed with DDS then StarTools. Calibration frames for the same duration (shorter flats) were used.
I have these two green hazy areas at different points on the photos. I thought I might have caught some nebulous gas but it's funny how it's in a different area on each of the photos.
The camera was an unmodified 450D with a CLS CCD filter.
Any ideas? (Scope was an 80mm refractor)
