Are you a "maker astronomer"? David Schneider describes his success in building an exoplanet tracker with a homemade barn door tracker and DSLR in IEEE Spectrum. With an inexpensive 2nd hand telephoto lens, free software, and a simple spreadsheet to do the differential photometery. David compared his target to nearby reference stars and was able to detect the gas giant HD 189733.

Deep sky observers should check out Brian Cuthbertson's Observing Targets for December.
