Jupiter Processing
See how stacking and processing techniques are used to take 5 pretty awful images of Jupiter and end up with one not-quite-so-bad image of Jupiter. Adobe Photoshop is the image processing tool used in this tutorial.

Photographing the Color of Stars
Demonstrates the technique of defocusing star trail shots (pioneered by David Malin) to bring out the color and temperature of the stars being photographed.

Anyone with a tripod and a camera that can be opened up for an extended exposure can try this out.

Photographing Iridium Flares
Discusses what is an Iridium Flare, and how to locate and photograph it.

All you need is a camera and tripod to get started. More advanced photographers will want to mount the camera on a tracking mount to eliminate any star trails during the extended exposure.
