Yay, another astronomy club meeting! And free doughnuts! Always worth the meeting, so to any Delawarian who reads this, come to Delaware Astronomical Society at Mount Cuba. Even if you hate astronomy with all your might, and just think that astronomy are for losers, there is dddoouuugghhnnuut. 😉
This month’s presentation was on errors in telescopes. While I would have liked it to be more science oriented, I still found it quiet interesting. Apparently, there is a gazillion ways for telescopes to be blurry. So yeah, what it says on the pic above.

What happens when the lens is slightly mis-shaped so that the wavefront arriving the eye is slightly off by 1/2 or 1/4 wavelenght of the light.
