M8-M20

I had already tried shooting, but their very low position on the horizon led me to abandon the idea. But given their low magnitude, I dedicated a few hours to them and I must say that they really deserve!
So I processed them and here are two of the most beautiful summer nebulae! The Lagoon Nebula or M8 and the Trifid Nebula or M20. The first is an emission nebula, the second, in addition to having an emission area, has a reflection component and a dark one, hence the name trifid.
The two nebulae are visible in the constellation of Sagittarius and are distant from our sun from 4000 to 5000 light years.
Instrumentation and shooting data:
