Description

This cosmic "brain" floating in a dense cloud of hydrogen has always been one of my favorite targets, but last year it didn't go that well...

So this year I decided to take more time on this subject and this what I've obtained with about 30h of data from my urban sky with and average SQM of 19.2!

RGB stars were obtained with a technque that me and my good friend Attilio put together in PixInsight, you can read more here (Italian only, but Google Translate should work just fine )
