A truly special object, really not much photographed due to the difficulties it presents: excluding the central part the rest is very weak. I invested several nights for shooting. Conditions have changed, but I tried to put it all together at best.
NGC1579 or "Trifid of the North", located in the Perseus constellation:

I hope you'll find it interesting.
All the best,
