I typically study asteroids, objects that are orbiting our sun and are typically on the order of several tens to a about a hundred kilometers in diameter.  When studying asteroids, the light that I am collecting in my camera typically takes a few minutes to travel from the asteroid to my telescope.

The light from the dominant object in the attached picture traveled 32,000,000 years to arrive at my telescope last night!  This object is known as Messier Object 74 or M74.  It is a spiral galaxy, orientated face on to my telescope.  The instrument I used to collect the light and record the image data uses a detector similar to your digital camera, with an array of 1024 pixels X 1024 pixels, for at total pixel count of just over 1,000,000 pixels.  Each tiny pixel in this image measures nearly 220 light years across! One could fit many hundreds of thousands of our entire solar system in just one of these pixels.

The image was acquired at the Via Capote Observatory, using 24, 2 minute sub-frames combined together.
