Oh, another exquisite beauty.

This is heavenly...just like chocolate at Easter.

I want to grab it and eat it too.

Thanks for sharing and all the hard work, Mr Rossolatos.
More please.

Just goes to show what 17 hours of exposure can get you.

Very nice.

Why is that the arms are always blue while the core is yellowy? Cooler stars are in the center?

Very nice.

Why is that the arms are always blue while the core is yellowy? Cooler stars are in the center?

Basically. The arms are dominated by bright young blue stars, while the central bulge is dominated by older reddish stars. This is because the arms have more gas and therefore more star formation.
