2MASS is an all sky survey that was started in 1997 and completed in 2001 with a final post processing release in 2003. 2MASS used northern (Mt. Hopkins, Arizona) and southern hemisphere (Cerro Tololo/CTIO, Chile) ground based telescopes to obtain data from the whole sky. Wavelengths around 2 microns, J (1.25 um), H (1.65 um), and Ks (2.17 um) in the Near Infrared (NIR) were used in this survey which produced over 500 million sources in the point source catalog and 1.6 million sources in the extended source catalog (I don't know what this means yet:) These catalogs are publicly available.
Probabley better in bullet form.
Add pics of actual scopes.
Add where it fits with other scopes and what it is typically used for???
