Hello everyone,
it's been a long time since I posted my last image, due to many reasons, the main one having no time to process my frames.
This one is another supoernova remnant (Sh2-224) with a nice emission nebula as neighbour. Sh2-223 in fact was at first thought to be another supernova remnant, but recent studies show that is "just" an emission enbula, despite the regular shape would recall the shock front of a supernova shell.
Dark and emission nebulas at the bottom left of the frame are not obviously physically part of those nebulas.
Here you may find the highres image and technical details of the shoooting session:

I very welcome comments and criticisms as usual.
Nicola
