The brighter yellow star makes a striking color contrast with its fainter blue companion star. Albireo is about 430 light-years away from the Earth.
“That’s purty.”
But I’ve looked into the night sky with and without a telescope and have never seen those colors. Therefore I don’t like the colors. The images show them but my eyes don’t.
Well, I guess they enhance the images to show what the stars really are IF you could see the variations with your eyes.
I was thinking of the spiral shape. But when I see these pictures I’m most impressed with just how many stars there are, and how many potentially have planets around them.
Even one galaxy, much less the Universe, is impossible to wrap one’s mind around...
That's very odd. I was just out last night under beautiful dark Arizona skies and was able to clearly see blue, reddish, gold, and orange stars with the unaided eye as well as through my telescope.
The human eye is not very good at seeing colors in dim light, which is why most astronomical objects appear black and white even through a telescope. Photos using time exposures can reveal more color, but what really brings them out is when color filters are used. The colors are real, just enhanced.

My Canon EOS R6 camera’s LCD screen can see the colors of nebula like the Orion nebula. The actual image captured is better. Full sensor digital cameras (35mm sensor) capture a lot of light. Add a big telescope mirror and even better.

Crews at the Department of Energy’s SLAC National Accelerator Laboratory have taken the first 3,200-megapixel digital photos – the largest ever taken in a single shot – with an extraordinary array of imaging sensors that will become the heart and soul of the future camera of Vera C. Rubin Observatory.
The images are so large that it would take 378 4K ultra-high-definition TV screens to display one of them in full size, and their resolution is so high that you could see a golf ball from about 15 miles away.
