Dear all, in the link below is a new HaOIIIRGB image from Coona, NGC 3199, another interesting object set in a very rich star field:

This time I didn't collect as much light as I usually do for other images, in particular on Ha and OIII, however, apart from a little noise higher than usual (I stretched a lot the narrowband trying to reveal all subtle nebular details), I am quite pleased with the result. It is quite interesting IMHO the interaction between OIII and Ha emissions on NGC3199 that produces a peculiar coloration of the nebula.
Details are on the related page.
I hope you will enjoy the view
Clear skies
Marco
