Rosette Nebula NGC2237

That's looking excellent Carole though I can't believe it's still got a little noise after all that exposure time.  Perhaps different stacking software or algorithm might be better ?  I'd check the borders and crop if necessary to prevent unnecessary comments about them in the future

I thought I had Robert, but I'll certainly be a bit more careful in future.

Yes it's bugging me too, might look into different stacking method and see what happens.
