Description

A hopefully improved version, originally captured in 2016, presented here as a ~70% crop from the 200mm widefield. The 1st processing is here: http://www.astrobin.com/261417/0/

I tried to improve a bit in sharpness and contrast, but I just liked the color of my 1st version so much, I reused most of its color data. What do you think, was it improved?

Constructive criticism, comments and suggestions are more than welcome in the comments section. Thank's for taking your time to look at this image.

Taken from Rural Skies (Bortle 3-4; NELM ~6.2; SQM ~21.4*calculated), from Cristina, MG, Brazil (22ºS latitude).
