Mars

We took a few pictures of Mars with a 7-inch Questar and an ST-5C CCD camera.

Focusing turned out to be the bottleneck; aiming was also hard. We do not think good quality is attainable without improving the hardware.


Authors::

• Meghan Oswalt and Morgan Weldon worked out the hardware and took half of images.
