NGC6888 Crescent Nebula - reprocessed

Crescent nebula and starfield showing some of the faint nebulosity around it. The Nebula has been produced by the Wolf-Rayet star in the center of the nebula.

20 * 300s unguided with the Sky90 + F/4.5 reducer/flattener. No Bias/ Flat or Darks.

After looking at some others on the web I decided that it needed a second look. It seems I got the black level far too high in Maxim so I've reprocessed to bring out the nebulosity that was hidden before.
