Thank you! Yes I have some other maps, but this is the first one with a large field. I drew it using a new technique. Some examples of other works that I done (with different techniques) are small detailed map for specific H II regions:

I have in mind to draw others new large field maps using the same new technique, I will post here when they are ready.
The colour of planetary nebulae: I think it's not a bad idea; probably a good colour will be purple. What do you think? Any suggestion?
