      Description

      SH2-71 or PK036-01.1 in Aquila
      I started this one mainly as a narrowband target but it is so detailed and contrasty in rgb that I only used very little of the Ha and OIII data.
      Anyway the narrowband data was useful for a little trick, usually with objects like this the rgb stars totally overwhelm the object.
      So in this case I used the narrowband stars and applied the rgb stars only as color layer in Photoshop.
      The nice thing is you get the rgb colors but with the reduced density of the narrowband stars.
      I usually downsample the images for display but this one is near the full system resolution.
      Hope you like it.
