I am using a 1000D with an ED127 and a 2" connector.
What is the best process for the flattening of images to reduce vignetting?

Frank, the duration of exposure doesn't affect vignetting, you'll need to start taking flats and get a field flattener for your scope (and of course stick to 2" adapters).
