And now for something
completely different! My first ever NB image - the Swan nebula (M17).
I won't complain about the poor seeing encountered when gathering the data - because I could

- or that I'm posting prematurely because I haven't acquired all the data yet (still need RGB and another 10 hours of NB), but what the hay! In any case, despite the poor seeing I teased out some reasonable structure I think.
Now I know why people like NB - it's so
easy to process!

No need to be a stickler for colour - just make it look good ... to yourself!
