M42-Orion Nebula/M43-de Mairan’s Nebula (Image 3) on 10/10/07

The other day I imaged the Great Orion Nebula and I posted two versions of the image that I did quickly that morning. This evening, I’ve had some time to restack the images in DeepSkyStacker. I’m starting to really understand better how to get the most out of this program. After restacking, the image showed a lot more detail than it had previously, particularly in the subtleties of the nebulosity and dust channels.

You may also notice the faint green haze around the outside of the nebula. The interesting thing about that is that through binoculars or my telescope, the nebula looks a faint greenish – there’s really no hint of purple or red, but as soon as I connected my camera, it’s clearly putting out quite a lot of red/purple light and the greenish tinge is really only seen around the edges. I’m not sure if this is the case in a more powerful telescope or not. Does anyone who has seen this through a more powerful telescope know the answer? Let me know.

Right now things are looking good for this evening, so I’m hoping to continue my Messier Hunt.



  1. Looks even better.

  2. I think you have pretty much captured all of the intense colors this neb has to offer.In the of the many images that I have taken,I have detected very little of the green color.I tried for this neb the other night/morning but,unfortunately my DSI and scope seem to get only a very close up image of the trapezium area.Next time we get a clear morning,I will bring out the DSLR which gives a nice FOV.
