I have lost count of how many times I have photographed and, above all, processed this nebula, but here I wanted to do something different. In fact, in this case, I put together all my shots from 2023 (taken with 2 different telescopes) with those of my "astro-delusional" friends Alessandro and Lino in order to reach a sufficient depth to go as deep as possible into this "stellar nursery". 
The subject is the nebular complex NGC 7822, also known as the Devil's Head Nebula, for which we accumulated almost 60 hours of total exposure. I am very pleased with the result, I hope you like it too.
