  1. Hi Stefano,

    very fine work on the nebulae structure. Did you edit the sketch only by hand or even with your software. Just for improving my own abilities ;-).

  2. Hello Torsten

    Thanks for the comment.

    I made ​​the drawing by hand. After scanning, I created a second level where I replaced the original stars. The design of the nebula was darkened, reversed.
    The nebula have added a Gaussian blur of 1.
    At the star field I added a Gaussian blur of 3.
    I merged the layers and created the presentation with the observation data.
    It ‘s all explained in my tutorial on my blog, but only in Italian, sorry.

    Stefano
