Description

Here the latest image from Messier at home project

http://www.arciereceleste.it/menu-profondo-cielo/118-progetto-m-h-messier-at-home

The orion nebula complex from my suburban sky.

Light pollution gradient correction on such a crowded fields is a real nightmare.

On this image I've used a multiscale technique described by Vicent Peris here  https://pixinsight.com/tutorials/multiscale-gradient-correction/

My reference image was an old shot taken from a dirn site in 2016:

Taste of winter
