Orion Nebula

[benklerk]

After having a very wet summer I managed to get more data of the Orion Nebula, after having hardware issues.




The Orion nebula is a is a diffuse nebula situated in the Milky Way, in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. It is about 1,344 light-years away, and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across.



The first image is your LRGB and the 2nd image is IR with G and B filters.

Hi Ben, I especially like the second as it's quite a different treatment - how is this done?

Hi Rob


I used the astronomik IR 742 filter to capture the IR spectrum. Then I when I combined it I dropped the red filter and used IR instead.



The main difference I can see is with the IR more stars are seen in the nebula which are hidden in the visible spectrum. The 2nd thing is, it shows the older redder cooler stars more easily as they shine more brightly in the IR part.

The intense orange on some of those stars in the IR shot is awesome!

Really well imaged and edited here.

Thanks Adam

I had to guess how to process the image, I just went with what the image told me and what felt right. Very little online on how to process IR with RGB filters.
