curves and levels using adjustment layers in CS3,
star saturation increase with Carbonis Actions,
color enhancement using Gabany method under CS3,
green cast elimination with Pixinsight LE 1.0,
gradient reduction with GradientXterminator,
final noise reduction of background and sharpening of nebulosity in CS3

These were the best imaging sessions on M45.
This image was a first attempt to stack frames from different sessions in IP 3.75.
