Glad to show you my last shot: Iris nebula.
This is the addition of two night sessions and processed with Siril, Darktable and GIMP.
Lights: 120 x 120" Darks : 12 x 120" Flats : 5 FS-60CB / Canon EOS100D
I used the synthetic bias integrated in the last version of Siril.
I love the dark nebula visible in the image.
