M8 M20 Redo with PixInsight

As many astrophotographers used PixInsight and drawn my attention for sometime. But for a slow learner and slow respondent like me, I needed to wait until the end of academic year! Anyway, I found that PixInsight is something like PhotoShop, which is huge in functions and the learning curve is long. This is my first piece of PI work. I used Registration, Dynamic Background Extraction, Background Neutralization and Color Calibration etc. In handling this image, I found that Background Neutralization is particularly useful! The result is simply great and make the final touch with Photoshop much more easy! I also attached a comparison between PI & DSS. The DSS version was processed a week ago.
