After 2 more nights now of clear but fairly hazy conditions I have managed to capture a bit more data including some SII. The result is that the Cygnus image is starting to come together. This version is a little bit over processed and there are some halos appearing around the stars.I’ll need to have another go at some point and mask the stars out before pushing the colour. Not sure yet whether this is best done in Pixinsight or Photoshop.
The colour mapping itself was based on Bob Franckes selective colour technique : http://bf-astro.com/hubblep.htm
I’m pretty pleased with the colour definition though
