Conclusion

Did you enjoy drawing the objects? You have now learned a little about what astronomy was like in my time. If you have a parent that owns a telescope, you can try doing astronomy just like I did. Look through the telescope's eyepiece, and draw what you see. Try it!


Part of the SDSS's camera

Today, astronomers rarely look through telescopes with their eyes. They almost always use a camera to record the data they want.

The SDSS telescope pictures you saw were taken with a large digital camera. The camera is shown to the right.

Question 8: Why do you think it is better to use a camera to take pictures of objects through a telescope instead of trying to draw what you see?

If you or your school has a scanner, try scanning your pictures into a computer. You can then "invert the colors" to make all the black areas white and the white areas black. If you did your drawing on a white paper, now you will have a black sky! To learn how to invert colors, see the Help menu of your photo editing program.

Send us your best drawings and we will post them in our gallery!
