McDonald Observatory Age of the Milky Way Workshop 2008

Imaging Data

This page contains astronomical images taken during the workshop. The data have been processed before posting on here; for raw data, please contact the organizers.

To get the data, right-click (PC) or ctrl-click (Mac) and save the FITS file to disk. Do not just click on the image, or you may crash your browser. If you would like to have a file in another format (like JPG), open the FITS file in ImageJ, adjust the brightness and contrast until you are happy, then save the image as a JPG.

You can make a pretty color image from these data using ImageJ; see Lesson 4 on the Learning ImageJ   page. Use the B band for blue, V-band for green, and R-band for red. For images without an R-band, use the B for blue, the V for red, and the BV for green (I created this by taking the square root of the product of the B and V images). You may want to change your images to a logarithmic stretch before combining them for more pleasing colors. (In ImageJ, go to Process -- Math -- Log).

Each image is about 16 MB in size; images of the same object have been aligned to make assembling color images simpler.
