Here we introduce one of the two standardized set of filters you will use on projects with BRIEF: SLOAN ugriz.

Saturation and Linearity are closely related in CCD imaging and need to be managed. A CCD pixel begins an image essentially empty. As the photons are collected, the pixel well begins to fill. At some point, the pixel well will become saturated and unable to hold more...

The following outlines the basics involved in acquiring an image of the night sky, whether for pretty pictures or scientific purposes. This lesson serves as an overview where other lessons will provide deeper instruction on the individual topics. This lesson provides...

Remembering from the CCD Overview lesson, each star: • Is the same size on the focal plane - a Point Source• Each point source has a specific shape and size at the CCD chip known as a Point Spread Function (PSF) • PSF is mostly determined by Seeing• Seeing is the...

Charged Coupled Devices (CCDs) were invented in the 1970s as memory devices. However, their light sensitive properties made them ideal for imaging applications. These improved light gathering power of telescopes significantly over what film cameras were producing....
