- Astronomy Boy — Jeff DeTray has some wonderful pictures of constellations he has taken with his barn-door tracker. His site is full of tips on how to construct your own tracker.
- QuickCam and Unconventional Astronomical Imaging — Focuses on the use of webcams for astronomy. Need specs on what your webcam can do? If anyone associated with astrocam has used one, you'll find it here.
- Christian Buil — This is home to Iris, information on building a spectrograph, a CCD camera, and more.
