I have always thought M45 looked like a blue tree when it is oriented this way. I have wanted to image it again for a few years now, but the weather always shuts me down. I was able to get enough data using the L:OSC technique. Oh, and as for the saturation, no one will ever accuse me of washed out colors, LOL!!!
