Seriously I wonder what humanity misses out on. I think we would have been a much better species if only we could see our place in the universe every night.

I do some astrophotography from time to time and it has been a great way to get away from it all to get some perspective while stargazing.

On occasion I venture out into dark sky areas in the US with friends, and they are always surprised that it is possible to see the milky way with the naked eye(or just so many stars at all).

The full panorama is spectacular: https://1.bp.blogspot.com/-LK-I6WIOp8w/YE3ejvMEc8I/AAAAAAAAS...

That's not the full panorama. Try https://1.bp.blogspot.com/-TqRxEAjrDYI/YFCLF-H8K3I/AAAAAAAAS... instead.

For folks passing through it's the full panorama but at 7% of the full resolution.

Are those colors real, or just synthesized by the visualization technique?

Real colors is always a particular definition, because everyone of us see the colors differently, for the astrophotography is another different thing because the colors are made by frequencies of the light spectrum.

> Conclusion on color calibration:

"There are multiple definitions of what it means to have ‘correct colors’ in your astrophotos. Therefor this always will be a matter of personal preference and everyone will have to figure out what their own vision on the matter is and pick a method of calibrating the colors accordingly"

Wow amazing work! The scale of this project reminds me of another photographer's five year project of creating a 2.5 gigapixel photo of Orion: https://orion2020v5b.spaceforeverybody.com/

This is fantastic.

I immediately wondered how he managed to seamlessly mosaic together what is surely hundreds of images and thousands of subs. Here are the details: https://space4everybody.com/processing-details/

And equipment: https://space4everybody.com/technical-details-equipment/

Nothing too fancy (in astrophotography relative terms). A decent refractor and mono camera (such parameters have come down in price by 2-3 times, ASI2600MM is comparable) and most importantly, a solid pier/mount.

  267 Individual panels (including reshoots)
  12,816 Individual light frames
  65,000 x 35,000 in it’s entirety
  5 States traversed to image
  640.8 Imaging hours
  500+ Editing hours
  2.5 Gigapixel Image
  1.6 Pixel scale
  5 Years
  1 Mosaic
Just WOW

Earlier quoted context omitted.

They are synthesized, from the article "Image in mapped colors from the light emitted by an ionized elements, hydrogen = green, sulfur = red and oxygen = blue."

What do the real colors look like?

To the naked eye from earth, it looks black and white, and you wouldn't be able to see that much detail. What they "really" are is more complicated, as indicated by other responses.

Very interesting article, well worth the read.

Damn, this is impressive. Wish there were more annotations of other notable sky objects in addition to what's shown.

Try https://1.bp.blogspot.com/-_0wX_SbN2V0/YFBrGdGEasI/AAAAAAAAS... for an image with more annotations.
