Description

Hi everyone!!

I want to share with you this rendition of M83 from my backyard under heavily polluted skies (bortle 9).
For this image I used the same technique that the last 2 images, that consist in stack an Optolong L-Pro flter with the LRGB filters.

I still can not believe that I can take this images from my backyard.

Hope you enjoy it, Clear skies, stay safe!
