Last night was my 1st attempt at widefield astrophotography with my Digital Rebel on a barndoor mount. Can anyone explain what went wrong? With exposures of about a minute or more the image starting saturating like it was overexposed (see example). Light pollution was minimal, with a street light at as house to my back.

Thanks for any suggestions
