Messier Catalog

This lab will be performed if time is permitting. It's also quite fun (I know, I keep saying that. I like the night labs, OK?) and if we get good images, you can get copies!

The point of this lab is to familiarize you with the Messier Catalog and the CCD camera on the 18" telescope. A CCD camera is essentially a digital camera (astronomers have been using this technology for about 2 decades). CCDs, as you'll learn, are far more efficient at taking astronomical images than film, and also give faster results. And they make pretty, digital pictures we can print or put on our web pages.

What I want you to do on this lab is to read the whole lab before coming to lab. The first two parts of the lab have questions for you to answer (just a few, not at all many). Then you get to select three (or more!) objects to image with the camera. I (or my co-observer) will move the telescope to your target and take your images for you. We'll get you printouts as quickly as we can (probably not that night, though). If they images are particularly good, we'll submit them to Keith Gleason for consideration for Picture of the Month.
