Description: 2X Drizzle for noise reduction. Applied a 2 pixel Gauss blur then resampled 50% (both in PS). This gives a much smoother image to start with although it did seem to lose a little color (mostly green).

Description: Cleaned-up some dry pixels in the core of the galaxy. Dry pixels from drizzle are common in bright low contrast regions.

Slightly increased the contrast in the M51b structures.
