Uranus
& Its Moons: |
The brightest object in this image is the planet, Uranus. The three star-like
objects very near Uranus are three of its moons. From left to right, they are
Titania, Umbriel and Ariel.
With HOU IP, open up the uranus_apo.fts image. Flip the image vertically so it matches this picture. Click on Log. Write down the (x,y) coordinates for Uranus and each of the moons.
This image was taken by Dave Cole of the
University of Chicago using the Apache Point Observatory telescope in New
Mexico. Dave operated the telescope by remote control using the Internet from
Adler Planetarium in Chicago on the evening of December 19th, 1997 (Dec. 20,
1997, 01:28 UT)

Uranus and Four Moons

In order to determine which were moons and which were stars the images were aligned on a star. So, when the images are added or subtracted you will see the planet and its moons change position. You can add or subtract images by using the HOU-IP software, Manipulation, add (or subtract), select a file, and click on display in a new window, OK. Here is the result. Use Data Tools, Slice to measure distances on the images. Use Data Tools, Aperture, choosing 4 and 8 for the settings, to compare brightness counts of the moons. |
