NGC7000 and IC5070: the North America and Pelican Nebulas. Taken with a monochrome camera and 200mm lens from a distance of ~1800 light years. Interesting fact - the North America Nebula covers an area four times the size of our full moon.

 

Thanks for looking!

I just applied SCNR to your image. Do you find this rendition more pleasing?

Just taste.  Personally I prefer the added structure definition of the original image, with more color.

Thanks for the comments!

 

SeymoreStars - I usually go through several versions before I select my final one. I do have one that looks similar, but in the end I felt like the detail on the one I chose. Sometimes it feels like we get rid of green just because we can, but it can also have its place. Both are nice, in the end it came down to personal preference. 
 

Sunnyday - thank you for your kind words. 
 

Bobzeq25 - thank you for your comments.

You do realize in the Hubble Palette, green = red?  <smile>

Cool image Ryan.

 

In my opinion, false color mapping of NB data is in the hands of the image processor who may choose SHO (Hubble), HOS, HaOHb, SNH, HOO, or their variations. Objectives could range from artistic to purely scientific. I think our ingrained expectations tend to play a role in what we may like/don't like, but not what is right or wrong when it comes to NB color mapping.
