I find also that most of your images tends to be more magenta than (for example) mine, so either we both need to check for color blindness  or simpler we are both right in giving our personal interpretations
A great image overall, up to your standards!

Thanks Marco, glad you liked it (mostly)
I have to say though, I actually thought you would find it ok

. When I look at your recent images of
Eta Carina and
The Running Chicken for eg, there is little difference in our vibrant colour balances. There is some suggestion however that the area around the Swan may be more dusty and hence slightly redder and thus less magenta than the Eta Carina and Running Chicken areas but yes, it's interesting...In relation to the
correct RGB "look" then Hydrogen nebulae are mostly magenta rather than true red, due to the HBeta influence (which is blue), it is the degree of saturation that is perhaps in question here?
Ok, on to the Chamaeleon Cloud...now that's not Magenta
