Namibia these wonderful nebulae are at zenith! That's another story
respect to the Italian skies, with low haze ruining the view of this
great field. The field is rich in star clouds, open clusters, emission
and reflection nebulae such as M8 and M20. The nebula at top-left is
Sh2-29, and the associated star cloud resembles a "giant foot" (Giant
Foot Nebula?), with a contour made with a dark nebula.

At first the focus was very good (FWHM 1.2) but at the end it was very bad (2.5).
