Wow wow wow, what a gorgeous, gorgeous, gorgeous APOD!
I know, It's a composite, composite, composite image, and the Carina Nebula could never look the way it does in the APOD. For one thing, details in the surrounding nebula have been very very much brightened, while Eta Carina itself has been dimmed by many magnitudes - or at least it looks that way! Hey, we can see the Homunculus Nebula! But, dimming and brightening aside, the details are gorgeous and the colors are to die for!
But let's compare the APOD to something a little more "normal-looking" to see what we are dealing with here:
As you can see, Johannes Schedler's image is more widefield than today's APOD. You can clearly see the main components of the Carina Nebula in Schedler's picture. Eta Carina itself is the bright yellow star at lower left of center in Schedler's image, and the large red round Keyhole Nebula, near center in the picture, clearly stands out. And while it is absolutely impossible to see the Homunculus Nebula in Johannes Schedler's image, many of the details in the surrounding field of nebulosities, like
the Finger of God, stand out clearly in Johannes Schedler's image.
Ah, but the APOD is so gorgeous! You knew I would love it.
