Howdy all
I thought Id make the most of a clear full moonlit sky and get out the 4Nm Ha filter again.
NGC 3576 is the larger nebula complex including the outer arcs mainly on right side of image, NGC 3603 is on the top just left of centre.
Its 3x15 mins (45 mins total imaging time) at ISO 400, Offset and dark subtraction in IRIS. Also I used only the red channel. Baader 4Nm HA filter and UV/R cut filter used.

Locating it was a challenge, as absolutely nothing could be seen through the viewfinder, so I used the finderscope to find it then took 1 min ISO 1600 shots to eventually get onto the right spot.

Narrowband filters are amazing beasts to use, the moon may as well not be there, though focussing is also a challenge (I was able to focus on Sirius, it was just bright enough)
