Saggitarius Milky Way core: Great!
Eta Carina: OK but ... saturation? busy? contrast? ... not sure what it is but feels a bit straining on the eye
The Large Magellanic Cloud: Great for 30s
6D was giving me this kind of result.
The Southern Cross: Nice, but like Eta the stars field is a bit overwhelming
Rho Ophiuchi: Stunning, not sure if this or the first is my favorite
