Overview: Students pick one of the target objects from their list from the previous activity and make an image request.
Consider working on a set of images from objects that already have been imaged in multiple filters. You can find sets here, Color Image Sets.http://sunra.lbl.gov/~vhoette/Explorations/images/edo/color/
Request new images in various filters using the Hands-On Universe Request system.
Make sure you request celestial objects that are in the midnight or morning sky. Early evening objects are likely to set before the telescope and imaging systems are ready to take your images.
