Description

The beautiful Iris nebula. It lies 1,300 light-years away and is six light-years across. The nebula gets its trademark glowing blue appearance thanks a star in the middle responsible for lighting it up. An interesting characteristic of this object is the intense interstellar dust around it clearly blocking out the stars behind it. (tech note: my longest exposure time of 106 X 10 minute "subs" captured over 3 nights = 17.6 hours of light capture...from my backyard)
