M51 stacked in DSS with Drizzle

This is the same image as the other M51 in the gallery. I decided to see what I could do with the data. I did the subtraction again this time without the Bias frames as the bias readout noise is already in the dark frames. I went with registar on the registration as it is the best ;), and used the Drizzle function in Deep Sky Stacker to stack the images and increase the size and resolution of the output image file. Turned out nice.
