ASTRONOMY PICTURES
Not many of them. I usually do Variable Stars and Eclipsing Binaries.

Galaxy NGC7331. Nucleus overexposed to show the faint outer spiral arms.
The Galaxy is 46,000,000 light years away. It was originally observed by William Herschel in 1784.

Galaxy NGC7331 Negative.
The same image as above, but the reversed image allows the spiral arms to be seen even more clearly.
There are some other galaxies in the picture, can you identify them?

Galaxy NGC7331 again, this time with the nucleus underexposed to show the
inner spiral arm region. In this picture you can see a faint inner spiral arm just outside
the bright central region.
Another "negative" image which makes those inner arms a little more prominent.
M57, the Ring Nebula. I've seen better images, but this one is mine. The ring is
caused by a dying star in the middle (faint and hard to see in this picture, if it's there). The
star is blowing off the outer layers of its atmosphere. The Sun will do this, about 5 billion years
from now, come next Tuesday.
