Cygnus HaRGB

The rich constellation Cygnus (Swan) is beautiful itself but through a 12nm Hydrogen-alpha clip filter it reveals a large amount of hydrogen nebulae.

 

This is my first "real" attempt to blend photos with a Ha filter and classic RGB images.

I tried to keep as much of the natural background as possible and at the same time get some extra nebulosity into the image.

There were a lot more nebulae in the Ha photo itself, but I decided to go for a more decent processing.

 

H alpha was photographed over two nights with a total time of more than 6 hours.

Even though Ha cuts off some wavelengths and "can be" photographed with the moon in the sky, it wasn't a good idea.

Weak details were not added not only because of the bright moon but also because of the wide field of view.

So next time i'll stick with the longer focal lenght :)

 

Despite the fact that there is not as much detail in the photo as I wanted, I am quite satisfied with it, but of course I will accept any criticism
