Description

A color re-shoot of Messier 45, the Pleiades aka the Seven Sisters.

My first shoot of this failed due to software removing the color unexpectedly. See that version and the writeup here:

http://astrob.in/full/43163/

Of all stellar clusters, this one in Taurus is most visible to the naked eye. These are very hot blue stars less than 100 million years old, about 400 light years away. The dust cloud is not related to the cluster, which is expected to be dispersed by gravity over the next quarter billion years.

May 25, 2013: As I look back on these early images as I move them from Flickr to Astrobin, this image is perhaps the first one I wouldn't be horrified by today. It isn't perfect, and I think I could do better with my current knowledge, but I am NOT changing old images. I am documenting my learning process. If I do re-do this original data (as I have done with at least two old images -- the Rosette and NGC 6946), I will re-post them under their re-processed dates as "new" images.
