Star Colors
I accidentally took a pretty cool picture of Orion last year back in Cabo. I was looking that this picture more closely to see how well you can see the color of the stars, image below. There are definitely some cool colors there: Betelgeuse is clearly red and Rigel is very bluish purple. Some of the other ones are a little surprising, especially the green ones. I expect these all to be "bluish" by definition. I wonder if these colors are real or are due to the flicker of the atmosphere; if I took a few more pictures, I wonder if the color would be the same?

Stars
Of the brightest stars in the night sky, which are the biggest? The smallest? How does their size compare to the sun? Which are closest? Furthest?
Some Messier Objects
If you wanted to list and compare some of the most popular, most beautiful Messier objects in the night sky, how would you do it? Below is my attempt. The hardest thing about thinking about astronomy is that I have no concept about where things are, where they are placed. Useful astronomical maps are lacking. These is one that I found on wikipedia that I found useful (though way too cluttered). I sketched the constellations out (and didn't label them) and marked the Messier objects on that sketch (nebula in red and galaxies in blue). To give some info I included their distances (in the log of light years) and comparing the distances on a single line.
Visualization of Our Solar Systems Most Important Moons
I've been trying to think of the best way to show the biggest / most important moons in our solar system. How do the following two visualizations help?
