COMMENTS
This is a "mouseover" image that allow us to compare the image I took of M31 with the images taken by the Ultraviolet/Optical Telescope aboard NASA's Swift spacecraft of the same object.
First you see the Swift image (not mine!) and if you move your mouse over the image, you can then see the image I took. Moving the mouse in and out of the image you can compare the two images.
I did this to see how the details in the core of my image matched those details - whenever visible - in the Ultraviolet image from the Swift spacecraft.
