A blood red Swan

When one shoots a swan, red color will appear.

So I did yesterday night, despite it is a protected animal (at least in the EU).

I used a Baader 7nm Halpha filter 2" in front of a canon EF 85mm f/1.8 squeezed to f/2.5 on a Canon EOS 6 and took 12 frames @ 4 minutes at 6400 ASA.
Darks and flats included.

Here I left the red color as desaturating (making a B/W image from it) loses some detail.

And here processed to b&w which succeeded without detail loss: Photoshop => Image => Black&White => Leave only red on:
