NGC 281 - More big images from small telescopes
NGC 281, an emission nebula in Cassiopeia SkyMap Pro gave me an excellent idea of the size and shape of this emission nebula but no real idea of its compexity. I was very surprised when I first saw the opaque, dark knots of gas and dust called "Bok globules" absorbing light in the center of the emission nebula. Near the globules is the young open cluster IC 1590 with its compact group of extremely hot, massive stars generating a strong stellar wind. The stars emit the visible and ultraviolet light that energizes the surrounding hydrogen gas in NGC 281. http://www.martin-nicholson.info/ngc281/ngc281.htm Martin Nicholson, Daventry, England. http://www.martin-nicholson.info/1/1a.htm Visit the Astronomical Hall of Shame at http://www.geocities.com/queen5658/ |
