NGC 604: Emission Nebula in M33

Click on image for larger version.

Discovered by William Herschel when the United States was still in its infancy. This HUGE nebula is actually in the galaxy M33. It has a diameter of 1500 light years and contains approximately 200 stars. Many of these stars have a mass several times that of our sun. M33 is about 3 million light years away from Earth.

  • Chris Schur (amatuer astronomer) put together a small image that identifies a few objects. Click HERE to see it.
  • The large file size is due to the fact I did not compress the image much for fear it would affect the small details.
  • Two iterations of L-R deconvolution (sharpening) algorithm using CCDsharp were applied to the luminance image.
