Notes: This is the Pleiades Open Cluster nicknamed the Seven Sisters which is a reflection nebula that gets its light from the surrounding stars.

I had just completed a long imaging session of the Crescent Nebula and decided to just take a test shot of M45 to see how many of the main stars I could fit in my field of view. So I just took one short 5 minute shot using a blue filter and this is the result. It turned out pretty good for just one short exposure and no stacking.

Another great photo, Rick!
I like the way the blue colour blends with the photo!

This refection nebula photographs best with a blue filter and doesn't really need a red or green filter as you would typically use for a full color image.
